It has since become a benchmark for acoustic quality, with thousands of units shipped from our workshop to the satisfaction of customers from all horizons (musicians, craftsmen, and manufacturers). They now equip instruments from the contrabass register to the tenor trombone of the most prestigious brands.<\/p>\n<p style=\"text-align: justify;\">In addition to collaborating with the best manufacturers, the workshop is constantly custom-building models for numerous musicians, offering them a full line of handmade trombones. This is made possible by the talent and expertise of our master craftsman Claudio Maragno, who maintains, repairs, and customizes all brass instruments. As a talented trombonist himself, no scheme seems too ambitious to challenge. He knows how to appreciate his client&#8217;s longing to having built a trombone that will meet his expectations.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=&#8221;.vc_custom_1731000063256{margin-top: 0px !important;padding-top: 0px !important;}&#8221;][vc_row css=&#8221;.vc_custom_1731000094809{padding-top: 20px !important;}&#8221;][vc_column]<div class=\"wpb_content_element \"><style type=\"text\/css\">#ut_header_6a093115d2b47 h2.section-title { font-size:18px !important;letter-spacing:0.1em;

It enhances the basic qualities of the trombone and eliminates its unevenness of emission.<\/p>\n<p style=\"text-align: justify;\">This exclusive tube-substitution concept ensures the air-column bypass with no restrictions on diameter or shape, allowing perfect air-flowing continuity. \u202fThe revolving inner rotor contains the tubes for the three deviations, welded in a bronze envelope, ensuring a minimum of mass, unlike conventional products.<\/p>\n<p style=\"text-align: justify;\">Perfectly ergonomic, safe, and silent, the valve is available in a wide choice of cylindrical or conical bores. From tenor to contrabass trombone, you will find the model best suited to your instrument, regardless your type of school: Vienna, Berlin, Dresden, Paris, New York, Boston, or Geneva.<\/p>\n<p style=\"text-align: justify;\">It is also the first and only brass instruments valve to feature a simple, efficient lubrication system that will insure protection and lifetime durability. Its utmost crafted construction features a brass casing housing a bronze inner rotor (alloys that have proven their perfect compatibility in this type of function for over 150 years). Combined with adequate lubrication, it guarantees long-lasting operation. Its long, small diameter treated stainless-steel swivel pin has a negligible wear rate, unlike conventional designs. The double-action spring (axial and radial) always guarantees the tightness of the (radial) face, while the (axial) diametral surface is perfectly adjusted by individual accurate honing.<\/p>\n<p style=\"text-align: justify;\">Each Hagmann valve is individually adjusted and checked. Utmost care is taken to ensure maximum tightness, a fundamental feature for perfect acoustics. Each one is identified by a serial number with traceability.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=&#8221;.vc_custom_1722615415357{margin-bottom: 60px !important;}&#8221;][vc_row][vc_column]<div class=\"wpb_content_element \"><style type=\"text\/css\">#ut_header_6a093115d9c30 h2.section-title { font-size:18px !important;letter-spacing:0.1em; }<\/style><header id=\"ut_header_6a093115d9c30\" class=\"section-header  ut-no-title-linebreak-mobile ut-no-lead-linebreak-mobile pt-style-7 header-center header-tablet-center header-mobile-center\"><h2 data-title=\"Valve design concept\"  data-responsive-font=\"section_title\" data-responsive-font-settings=\"{&quot;base-font-size&quot;:&quot;global&quot;,&quot;font-size&quot;:{&quot;desktop_large&quot;:&quot;18&quot;},&quot;base-line-height&quot;:&quot;global&quot;,&quot;base-letter-spacing&quot;:&quot;global&quot;,&quot;letter-spacing&quot;:{&quot;desktop_large&quot;:&quot;0.1&quot;}}\" class=\"section-title  \"><span>Valve design concept<\/span><\/h2><div data-delay=\"0\" class=\"lead \"><p>The 3-bypass valve is illustrated below:<\/p>\n<\/div><\/header><\/div>[vc_row_inner equal_height=&#8221;yes&#8221; content_placement=&#8221;middle&#8221; gap=&#8221;20&#8243;][vc_column_inner width=&#8221;1\/2&#8243;]<div  class=\"wpb_content_element   vc_custom_1726504007909 clearfix\"><style type=\"text\/css\">#ut_am_6a093115dba0e { opacity: 1; }#ut_am_wrap_6a093115dba0f .ut-image-gallery-item-caption-title h3 { letter-spacing: 0em; }#ut_am_wrap_6a093115dba0f .ut-gallery-slider-caption { font-weight: bold; }#ut_am_wrap_6a093115dba0f { text-align: center; }@media (min-width: 768px) and (max-width: 1024px) { #ut_am_wrap_6a093115dba0f { text-align: center !important; } }@media (max-width: 767px) { #ut_am_wrap_6a093115dba0f { text-align: center !important; } }<\/style><div id=\"ut_am_wrap_6a093115dba0f\" class=\"ut-image-gallery-image \"><div id=\"ut_reveal_6a093115dba10\"  data-appear-top-offset=\"auto\" class=\"ut-animated-image-item ut-image-gallery-item ut-animation-done \"><a class=\"ut-deactivated-link\" href=\"#\"><div class=\"ut-animated-image-zoom\"><img decoding=\"async\" class=\"ut-lazy skip-lazy ut-animated-image \"  id=\"ut_am_6a093115dba0e\" src=\"data:image\/svg+xml;charset=utf-8,%3Csvg xmlns%3D'http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg' viewBox%3D'0 0 400 600'%2F%3E\" data-src=\"https:\/\/www.renehagmann.ch\/wp-content\/uploads\/2024\/09\/rot1.gif\" width=\"400\" height=\"\" alt=\"\"\/><\/div><\/a><\/div><\/div><\/div>[\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243;]<div  class=\"wpb_content_element   vc_custom_1726503972971 clearfix\"><style type=\"text\/css\">#ut_am_6a093115dcd6d { opacity: 1; }#ut_am_wrap_6a093115dcd6e .ut-image-gallery-item-caption-title h3 { letter-spacing: 0em; }#ut_am_wrap_6a093115dcd6e .ut-gallery-slider-caption { font-weight: bold; }#ut_am_wrap_6a093115dcd6e { text-align: center; }@media (min-width: 768px) and (max-width: 1024px) { #ut_am_wrap_6a093115dcd6e { text-align: center !important; } }@media (max-width: 767px) { #ut_am_wrap_6a093115dcd6e { text-align: center !important; } }<\/style><div id=\"ut_am_wrap_6a093115dcd6e\" class=\"ut-image-gallery-image \"><div id=\"ut_reveal_6a093115dcd6f\"  data-appear-top-offset=\"auto\" class=\"ut-animated-image-item ut-image-gallery-item ut-animation-done \"><a class=\"ut-deactivated-link\" href=\"#\"><div class=\"ut-animated-image-zoom\"><img decoding=\"async\" class=\"ut-lazy skip-lazy ut-animated-image \"  id=\"ut_am_6a093115dcd6d\" src=\"data:image\/svg+xml;charset=utf-8,%3Csvg xmlns%3D'http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg' viewBox%3D'0 0 400 600'%2F%3E\" data-src=\"https:\/\/www.renehagmann.ch\/wp-content\/uploads\/2024\/09\/rot2.gif\" width=\"400\" height=\"\" alt=\"\"\/><\/div><\/a><\/div><\/div><\/div>[\/vc_column_inner][\/vc_row_inner][vc_row_inner equal_height=&#8221;yes&#8221; content_placement=&#8221;middle&#8221; gap=&#8221;20&#8243;][vc_column_inner width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1722615453836{padding-top: 0px !important;padding-bottom: 0px !important;}&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<p style=\"text-align: justify;\">The numerous angles and passage restrictions of traditional valves disrupt the air column. This results in irregular emission and tone with increased resistance. As the Hagmann valve has no restrictions on the air column, no angles and no excessively sharp bending radiuses of the internal ducts, the emission is full and easy, very homogeneous through all registers from pianissimo to fortissimo.<\/p>\n<p style=\"text-align: justify;\">Since the 70s, there have been various attempts to improve the acoustics of the traditional valve. With his own, Ren\u00e9 Hagmann pays tribute to another enthusiast, Ed Thayer, a pioneer indeed, but one whose creation was perfectible in terms of maintenance, if only regarding the complex lubrication involved with his design.<\/p>\n<p>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243;

Evaluated by numerous top professionals, this design has proven to be the state-of-the-art concept.<\/p>\n<p>For technical and simplification reasons, the traditional bore through the two F and D valves is cylindrical, about 15.0mm to match both wraps.<\/p>\n<p>In principle, the air column section linking the playing slide to the main tuning slide should be conical, as on a single Bb tenor. Our approach is to reproduce as closely as possible the ideal conical bore progression through both valves.<\/p>\n<p>The tonal balance resulting from this highly refined concept evidences the relevance of our approach. The unique combination of interior geometry, manufacturing knowledge and experimentation has given birth to a genuine evolution in the bass trombone design.<\/p>\n<p>This set features a conical progression through the two valves, with Bb passages ranging from 14.6 to 15.5mm. Operation with the 15mm F and D wraps is very balanced. This unique design improves overall sound emission and homogeneity. Even when playing pianissimo notes, the low register is optimally fluent, while the tenor segment is more consistent.<\/p>\n<p>Tests in concert halls have also demonstrated a superior projection in comparison with our traditional cylindrical sets. This kind of set-up is ideal for symphonic and contemporary music.<\/p>\n<p>The unique design of this \u201cprogressive bore\u201d set is only made possible with a 3-way concept which is the benchmark of the Hagmann valve.<\/p>\n<\/div><\/div><\/div><div data-accordion data-accordion data-single data-transition=\"400\" data-easing=\"ease\" class=\"ut-accordion-module-item \"><h3 data-control class=\"ut-accordion-module-heading\" data-counter=\"2\">The Two Steps bass trombone valve set (TSBF) <\/h3><div data-content class=\"ut-accordion-module-content\"><div class=\"ut-accordion-module-inner entry-content clearfix\"><p>The \u201cTwo Steps\u201d design is somewhat derived from the concept of the progressive bore, but instead of being almost continuously conical, it more simply consists of two different successive bores. The F valve features a 14.8mm Bb bore, and the D sports a 15.2mm Bb bore. On the other hand, both the F and D knuckles, share the same15.0mm bore.<\/p>\n<p>This two-step design gives excellent ease of emission, a slightly brighter sound than the progressive bore, but also very well centered. This model has therefore also been selected, manufactured, and sold to the entire satisfaction of many professionals and knowledgeable amateurs.<\/p>\n<\/div><\/div><\/div><div data-accordion data-accordion data-single data-transition=\"400\" data-easing=\"ease\" class=\"ut-accordion-module-item \"><h3 data-control class=\"ut-accordion-module-heading\" data-counter=\"3\">Weekly valve maintenance<\/h3><div data-content class=\"ut-accordion-module-content\"><div class=\"ut-accordion-module-inner entry-content clearfix\"><p>The valve should be lubricated once a week with trumpet piston oil. We have had excellent experience with \u201cLa Tromba T2\u201d brand. Do not use French horn rotary valve oil, which is often too viscous, or oils that are too volatile (e.g. Al Cass).<\/p>\n<p><strong><img alt=\"\" alt=\"\" loading=\"lazy\" decoding=\"async\" class=\"wp-image-735 aligncenter\" src=\"https:\/\/www.renehagmann.ch\/wp-content\/uploads\/2025\/10\/calque-carte-cylindres-1.jpg\" alt=\"\" width=\"306\" height=\"350\" srcset=\"https:\/\/www.renehagmann.ch\/wp-content\/uploads\/2025\/10\/calque-carte-cylindres-1.jpg 900w, https:\/\/www.renehagmann.ch\/wp-content\/uploads\/2025\/10\/calque-carte-cylindres-1-768x877.jpg 768w, https:\/\/www.renehagmann.ch\/wp-content\/uploads\/2025\/10\/calque-carte-cylindres-1-630x720.jpg 630w\" sizes=\"auto, (max-width: 306px) 100vw, 306px\" \/>Proceed as follows:<\/strong><\/p>\n<ol>\n<li>Remove the A engraved cap by holding it between your fingers on its knurled edge.<\/li>\n<li>Put about the equivalent of 10 to 12 drops of oil inside the D casing and one drop on the gasket holding the lid.<\/li>\n<li>Put a drop of oil on the stem outlet, underneath the spring, position C.<\/li>\n<li>Press the A cap back into place.<\/li>\n<li>Action the valve several times by lightly pressing on the B flange while orienting the valve as follows: A up (ceiling), B down (floor).

During your weekly lubrication, cautiously remove excess water before renewing lubrication.<\/p>\n<p>We recommend that you have your trombone checked and serviced every 2 years by a qualified repairman.<\/p>\n<\/div><\/div><\/div><\/div><\/div>[\/vc_column][\/vc_row][\/vc_section]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_section full_width=&#8221;stretch_row_content&#8221; content_placement=&#8221;middle&#8221; bklyn_overlay=&#8221;true&#8221; bklyn_overlay_pattern=&#8221;true&#8221; bklyn_overlay_pattern_style=&#8221;bklyn-style-two&#8221; parallax=&#8221;content-moving&#8221; background_position=&#8221;center center&#8221; css=&#8221;.vc_custom_1722357098879{background: #000000 url(https:\/\/www.renehagmann.ch\/wp-content\/uploads\/2024\/07\/img-title-ondes-music.jpg?id=45) !important;}&#8221; bklyn_overlay_color=&#8221;rgba(0, 0, 0, 0.5)&#8221;][vc_row][vc_column][\/vc_column][\/vc_row][\/vc_section][vc_section content_placement=&#8221;middle&#8221; parallax=&#8221;content-moving&#8221; parallax_threshold=&#8221;-30&#8243; background_position=&#8221;left center&#8221; hide_bg_tablet=&#8221;true&#8221; hide_bg_mobile=&#8221;true&#8221; css=&#8221;.vc_custom_1731511481859{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;padding-bottom: 0px !important;background-position: center !important;background-repeat: no-repeat !important;background-size: contain !important;}&#8221;][vc_row equal_height=&#8221;yes&#8221; content_placement=&#8221;middle&#8221; css=&#8221;.vc_custom_1731511490875{margin-top: 0px !important;margin-bottom: 0px !important;border-bottom-width: 0px !important;padding-top: 0px !important;}&#8221;][vc_column width=&#8221;1\/2&#8243; offset=&#8221;vc_col-lg-6 vc_col-md-6 vc_col-sm-12&#8243; css=&#8221;.vc_custom_1731511503310{margin-top: [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_seopress_robots_primary_cat":"","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","footnotes":""},"class_list":["post-759","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/pages\/759","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/comments?post=759"}],"version-history":[{"count":2,"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/pages\/759\/revisions"}],"predecessor-version":[{"id":761,"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/pages\/759\/revisions\/761"}],"wp:attachment":[{"href":"https:\/\/www.renehagmann.ch\/en\/wp-json\/wp\/v2\/media?parent=759"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
