Freudenberg Sealing Technologies recently partnered with Definox to develop a series of high-performance seals for butterfly valves.
Definox produces valves and stainless steel equipment for the process industry and needs a sealing solution to develop a new series of high-performance butterfly valves. The French-based company and Freudenberg Sealing Technologies combined their expertise and materials to develop 70 EPDM 291 O-rings.
“We convinced our customers with our new high-performance butterfly valve seals tailored to meet specific requirements, so they asked us to start replacing existing valve type seals,” said David Brenière, process industry sales manager. Freudenberg sealing technology.
The butterfly valve seal adopts a combination of wear-resistant materials, with little force when closing. When closed, the valve has a high compression to ensure that it seals properly. The sealing geometry has also been developed to have no dead ends and no leakage to achieve a hygienic design.
Freudenberg and Definox butterfly valves are available in three FDA and EU (VO) 1935/2004 compliant materials: 75 EPDM 253356, 75 Fluoroprene XP 41 and 75 HNBR 254067. 75 Fluoroprene XP 41 has undergone additional in vivo testing according to USP Chapter 88 121°C and passed VI level certification, in line with BNIC’s 3-A sanitary standards and regulations
