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.

841T / 842T PTFE Lined for chemical duties with a proven record of excellent performance and long life in heavy duty applications.

The 71LG provides 16 BARg fully rated lugged pattern valves up to DN600 (24″) The renowned TOMOE cosine seat design ensures reliable and consistent sealing at a fully rated 16 BARg pressure application. Multi layered stem bearings and unique disc design ensures reliable sealing and less torque. Higher Cv values and pressure loss figures at the fully open position are significantly lower than those of competitors. Field replaceable seat ring makes maintenance easy and reduces maintenance costs.

A wafer or lugged pattern, rubber seated butterfly valve. The seat is vulcanised to the valve body, and incorporates a modified cosine curve seat profile. This provides lower torque, reduced friction and improved flow characteristics, especially at the partially open position.
The vulcanised seat also ensures improved performance under high velocity and vacuum conditions.

BUTTERFLY VALVE  705G Semi lugged – For low pressure applications including, sand, cement powder, sea water, waste water, sugar processing, general food industry, fertiliser spraying, carbon black, low vacuum and compressed air. Valve Nominal Size: 50mm to 200mm, 250mm to 300mm, 350mm to 500mm and 600mm.

BUTTERFLY VALVE 704G full lugged  – For low pressure applications including, sand, cement powder, sea water, waste water, sugar processing, general food industry, fertiliser spraying, carbon black, low vacuum and compressed air. Valve Nominal Size: 50mm to 200mm, 250mm to 300mm, 350mm to 500mm and 600mm.

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.

Fully PFA lined butterfly valve with either stainless steel encapsulated, or PPS disc.
A chemically resistant butterfly valve. Design features of the 846T,847T result in low torque, superior strength and sealing properties, essential in applications where conditions are potentially hazardous. Size: 50mm to 200mm or 250mm to 300mm. Working Temperature Range: Intermittent = -20 to +200 C, Continuous = 0 to +150 C.

This lightweight, cost effective butterfly valve is ideally suited for applications up to 10 Barg. The superior leaktight properties are achieved by using the proven 16 Barg rated 700G disc and seat within a lightweight body. The 773Z valve conforms to ISO5752 face-to-face dimensions and ISO5211 actuator mounting flange.

BUTTERFLY VALVE  700G Wafer – Low pressure applications including, sand, cement powder, sea water, waste water, sugar processing, general food industry, fertiliser spraying, carbon black, low vacuum and compressed air. Valve Nominal Size: 40mm to 200mm, 250mm to 300mm, 350mm to 500mm and 600mm.
