This Isn’t Just Another Butterfly Valve

Robin Daughtry | January 25th, 2012

The WAFER-SPHERE from Jamesbury is not just another Butterfly Valve

It is a high-performance valve that offers significant performance, weight, size and cost of ownership advantages. The WAFER-SPHERE provides a cost-effective solution for a wide variety of applications where bubble-tight shut-off is required in manual, automated and proportional services with temps from -320°F to 500°F and pressures to 1480 psi.  It’s unique design is an extension of sealing technology – utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body resulting in a tight-sealing, yet lower-cost alternative to gate valves and other rotary valves.

WAFER-SPHERE High-Performance Butterfly Valves – The Gate Crasher

The WAFER-SPHERE eliminates all the reasons for using gate valves except one: Habit!

The Automated WAFER-SPHERE has low profile compared to
competing gate valve
