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.
