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.
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.
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.
