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 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.
