Vridspjällventil 302A,303Q Firesafe (Butterfly Valve302A,303Q Firesafe)
Double Offset, metal seated Fire-safe valves to API standards. The range is certified Fire-safe to API 607 4th edition, and is available in both wafer and lugged pattern bodies.
This high performance butterfly valve is suitable for bi-directional flow, and the disc is designed to reduce thermal expansion, thus providing constant sealing performance against temperature and pressure cycling conditions.
Vridspjällventiler 304Y RPTFEsäte (Butterfly Valve 304Y RPTFE Seat)
The 304Y high performance butterfly valve has a distinctive “J” shaped PTFE seat ring which does not detract from the rigidity of the valve mechanism, yet provides a more user friendly torque profile – but without sacrificing durability or leak tightness. In common with its stable companion, the 302Y, this valve complies with face-to-face ISO5752 and ISO5211 mounting flange requirements. Nominal Size: 40mm to 150mm, 200mm and 250mm to 300mm. Working Temperature Ranges: -20 C to +200 C.
Vridspjällventiler 302Y metallsäte (Butterfly Valve302Y Metal Seat)
Designed for operation in high pressure/high temperature environments, the 302Y high performance butterfly valve features several unique features which combine precision engineering with advanced design (eg self-aligning, high rigid thin-wall disc and “ball lock” seat retainer) to produce the ideal replacement for conventional metal seating gate and globe valves. Size: 40mm to 150mm, 200mm and 250mm to 300mm. Working Temperature Ranges: -20 C to +250 C.
