Manual Ball Valves in PVC, CPVC, PVDF & Polypro

Known worldwide as the Engineered Ball Valve

Design Advantages:

  1. Heavy-duty, extra-large diameter shaft is reinforced by additional resin and eliminates stem breaks.
  2. Double shaft O-rings.
  3. PTFE shaft bearing eliminates friction and wear.
  4. PTFE seats backed up with O-rings reduce the wear and tear of repeated cycling.
  5. Trunnion Design: Upper and lower supports retain ball under pressure. Trunnion design allows multi-directional flow; means that the valve is in no danger of being installed "backwards."
  6. Concentric machined and mirror-polished ball.
  7. Dual sliding seats use triple O-rings for balance and maximum leak protection.
  8. Smooth flow path eliminates pressure loss.
  9. True union ends for ease of piping and removal.

Series EBV -- Actuated Ball Valves -- Electrically powered actuators for 2-way and 3-wayball valves, all sizes. Features Standard Manual Override.

Series ABV -- Actuated Ball Valves -- Pneumatically or hydraulically powered actuators for2-way and 3-way ball valves, sizes 1/2", 3/4", and 1". Air x air and "failsafe" air x spring models available; converts easily between types. Manual override standard.

Series ABR -- Actuated Ball Valves -- Pneumatically or hydraulically powered actuators for2-way and 3-way ball valves, sizes 1-1/4", 1-1/2", and 2". Air x Air and"fail safe" Air x Spring models available. Manual override standard on air x air, optional on air x spring version. Air x spring converts easily between fail safe "open" and fail safe "closed."

Series TMBV -- 3-Way Manual Ball Valves offering all of the features found in the 2-Way valves above. Offered in PVC and CPVC.

Series TEBV -- Electrically Actuated Ball Valves 3-Way Electrically-Actuated Ball Valves, for installations where compressed air or hydraulic power is not available or practical.

Series SW --Limit Switches -- For use with actuated ball valves.

Air-Operated Diaphragm Valves and Globe Valves-Perhaps your application requires more rapid shut-off, or you want to use line pressure to open the valve, or have other reasons you don't specifically want a ball valve. If so, True Blue ASO, BSD, or BSR may meet your needs.

Online Pressure Drop Calculator -- Allows you to easily determine the probable pressure drop across a valve. Note: For comparison and illustrative purposes only; not to be relied on for system design.
