Weir entry Double Offset High Performance Valve,available Class
150- 900. Valve is available with Varidiff Trim, if cavitation is a
problem. Valve is available for Cryogenic applications ( see
BV36000 ). The seal design and valve geometry
combine to ensure a uniform 360° seal contact in the closed
position and the double eccentric action moves the disc into and
out of the seat with the minimum of wear and seating torque.
The 90° on/off action allows for fast
operation when necessary and the low torque characteristics are an
economical advantage in power operation. When fitted with a
suitable positioning actuator, the valve can perform a dual
purpose. The design of the Hyperseal makes it ideally
suitable for use on cryogenic service down to -1960C, and it can be
supplied with cold bonnets to suit the customers
Features / Benefits
- Double eccentric action moves the vane into and out of the seat
with minimum wear and seating torque, giving longer seat life and
reduced overall valve torque.
- Valve is suitable for both Isolation and control
applications,readily removable seat retaining ring allows for quick
and easy replacement of valve seat ring.
