Chemtrol Tru-Bloc Series: Manually Actuated - CPVC \ FKM

The True Union feature, an exclusive Chemtrol® introduction over twenty years ago, has become an industry standard. Coupled with its other features, the Chemtrol® Tru-Bloc™. True Union Ball Valve adds up to great versatility and significant savings in operating and maintenance costs. Chemtrol® Tru-Bloc™ True Union Ball Valve’s heavy-duty stub-acme thread-seal carrier retaining ring provides more reliability than other designs. Double-block design stops flow in either direction - upstream and downstream - when the alternate union is removed for servicing of the system.

Georg Fischer Type 304 Y-Check Valve is a weighted angle check valve and is used to automatically stop flow in the reverse direction when the fluid in the line stops. The valve closes by the dead weight of the weighted seat and functions when mounted in either the horizontal or vertical plane.  Type 304 Y-Check Valves are superior to spring-loaded checks for corrosive service since they are not temperature sensitive. Y-Check valves generally have tighter shut-off characteristics than ball check valves at the same pressures. Georg Fischer Type 304 Y-Check Valves feature a transparent PVC construction which allows for inspection of the position and condition of the valve piston and seat.
