The valve is a bi-directional tight shut-off device incorporating a resilient seal mechanically retained around the periphery of the valve disc. The seal is available in various types of elastomers, the selection being dependant on the valve duty and working pressure and temperature. The seal seats against a metal seating surface machined into the body of the valve.

Bi-Directional Shut-off device

The valve is a bi-directional tight shut-off device incorporating a resilient seal mechanically retained around the periphery of the valve disc. The seal is available in various types of elastomers, the selection being dependant on the valve duty and working pressure and temperature. The seal seats against a metal seating surface machined into the body of the valve. Positive shut-off is achieved without excessive interference between seat and seal ensuring maximum seal life and low seating and unseating torques.
