Ball Valves & Actuation
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.
Spears® True Union 2000 Ball Valves provide maximum versatility with fully interchangeable (with Series 2000 Ball Check Valves and 3-Way Ball Valves) valve cartridges. Provides for easier system design modifications and upgrades in multi-phase projects, or anywhere changes in valve type are desired. All True Union 2000 valves feature a low-profile, compact design for minimal space requirements. Choice of high grade EPDM or Viton® o-rings allows application-specific selection for optimum chemical resistance.
