Series P Pneumatic Isolation Valves Air Operated

Series P Pneumatic Isolation Valves


Air Operated, Two Way & Three Way

DESCRIPTION
Model series P pneumatic isolation valves are pressure actuated and have orifice sizes from 1.6 to 25 mm.

The valves are particularly suitable for applications where use of air instead of electricity makes sense such as explosive and inflammable environments.

*All models except model PBF-R rely on a spring to return to normal state when pressure
  is relieved. Model PBF-R is spring-less and unbiased. It requires air pressure to effect a
  change of valve state.

OPTIONS

Consult us for the following options:
  -Flow rate adjuster
  -Reverse suction configuration immediately shuts off flow by sucking back
  a small volume of liquid when changing valve state
  -By-pass structure circulates fluid in valve to prevent bacterial growth.
