Butterfly Valves

Our butterfly valves are low torque acting, quarter turn rotary action where the fluid run straight through.
The disk is turned in axial trunnion bearings in a single seat and intrudes into the flow passage in the fully open position. Seats may be soft or metal.

We supply two main types:

Conventional – shaft passes through the disk axis and they are generally soft (elastomer)
seated for low pressure;
High Performance – with offset disk/seat and soft or metal seated for high pressure
