PNEUMATIC ACTUATORS TYPE P1/R1

APPLICATION AREA:
The multi-spring diaphragm pneumatic actuators of P1/R1 type are applied for control operation of control valves and other positioning elements in industrial automatic systems. There are three design options of the acutators:
  • direct action (air - ejects the stem) - type P1,
  • reverse action (air - retracts the stem) - type R1,
  • direct action, handwheel - type P1B,
  • reverse action, handwheel - type R1B

FEATURES:

  • completely reversible action, option to change spring range w/o extra parts,
  • rigid structure of cast yoke,
  • wide range of available forces,
  • linear dependence of stem movement from control pressure, due to application of diaphragms with constant effective area,
  • various spring ranges achieved by changing the number of springs and/or changing position of spacer elements,
  • capability of the actuator to incorporate side-mounted handwheel, pneumatic or electro-pneumatic positioners, limit switches, air sets, three-way pneumatic solenoid valves, lockup valves, position transducers,
  • high strength of diaphragms, springs and packings,
  • low weights and small overall dimensions.
