This wave uniformly cleans the entire length of the filter bag. High peak pressures are achieved with significantly reduced air consumption. The result is a highly <strong>efficient<\/strong> <strong>and effective<\/strong> improvement of <strong>filtration systems, making them innovative and sustainable.<\/strong><\/p>\n<p>Thanks to this cutting-edge technology, Trimec<strong> SPV valves<\/strong> can effectively clean filters up to <strong>12 meters in length<\/strong>, enabling up to <strong>40% more filtering surface area<\/strong>.<\/p>\n<p>Our line of low-pressure SPV valves ranges from 2\u201d to 3\u201d1\/2.<\/p>\n<p>Valve selection is defined in the initial design phase by our team based on the number and size of filter elements that each valve must effectively clean.<\/p>\n<p><strong>Do not hesitate to contact us<\/strong> for any queries regarding Trimec brand <strong>valves<\/strong>.

Low-pressure piston valves<\/nav>Low-pressure piston valves Certified Tanks with Integrated Piston Valves for Cleaning Filter Elements at Low Pressure Trimec has been active in the filtration field for over 15 years, developing valves, control units and accessories for dedusting systems The Sonic Piston Valve is the product that best represents the TRIMEC technology. Designed for high-performance cleaning of filter elements, the valve operates at low pressure (2\u20133 bar max) and features a direct airflow path that generates a sonic wave. This wave uniformly cleans the entire length of the filter bag. High peak pressures are achieved with significantly reduced air consumption. The result is a highly efficient and effective improvement of filtration systems, making them innovative and sustainable. Thanks to this cutting-edge technology, Trimec SPV valves can effectively clean filters up to 12 meters in length, enabling up to 40% more filtering surface area. Our line of low-pressure SPV valves ranges from 2\u201d to 3\u201d1\/2. Valve selection is defined in the initial design phase by our team based on the number and size of filter elements that each valve must effectively clean. Do not hesitate to contact us for any queries regarding Trimec brand valves. We\u2019re at your service, operating actively throughout Italy.2\u201d [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":4412,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"dipi_cpt_category":[],"class_list":["post-4425","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Low-pressure piston valves-Dedusting filter cleaning systems<\/title>\n<meta name=\"description\" content=\"Low-pressure piston valves designed by Trimec enable effective and sustainable cleaning of dedusting systems.
