Pilot Operated Check Valves 27 Series Product Overview

Pilot Operated Check Function
Pilot Operated Check valves are used for load holding or cylinder position holding applications, designed to trap pressure in order to hold a cylinder in place when a safety event occurs.
Pilot Operated Check valves can be used wherever a high-flow or remotely-controlled checking function is needed. Can be used in a circuit to provide automatic stopping of a cylinder in the event of the loss of electrical or pneumatic power.

Applications

Solenoid Pilot Controlled Valve Application
Dual Pilot Operated Check Valve Circuit Features

  • To operate cylinder, simultaneously energize solenoids A and C or B and C.
  • Pilot supply and exhaust are independent of control valve.
  • Response time is not affected by exhaust restrictions of the control valve.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if electrical signal is lost.
  • Pressure in cylinder is exhausted when the air supply at “P” port is lost or locked-out.
  • L-O-X® valve provides lockable shut-off of air supply, and exhausting of trapped downstream air
Pressure Controlled Valve Application
Single Pilot Operated Check Valve Circuit Features

  • Cylinder moves as long as the control valve solenoid is energized. Use for continuous motion or jogging.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if electrical signal is lost.
Single Pilot Operated Check Valve Circuit Features

  • Cylinder moves as long as the control valve solenoid is energized. Use for continuous motion or jogging.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if electrical signal is lost.
Single Pilot Operated Check Valve with Trapped Pressure Relief Application Circuit Features

  • Trapped pressure between check valve and cylinder is exhausted when the air supply at the
  • Blowdown Signal Port (BP) is lost or locked-out.
  • Cylinder moves as long as the control valve solenoid is energized. Use for continuous motion or jogging.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if electrical signal is lost.
Pressure Controlled Valve Application
Single Pilot Operated Check Valve with Manual Trapped Pressure Relief Circuit Features

  • To operate cylinder, simultaneously energize solenoids A and C or B and C.
  • Pilot supply and exhaust are independent of control valve.
  • Response time is not affected by exhaust restrictions of the control valve.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if electrical signal is lost.
  • Pressure in cylinder is exhausted when the air supply at “P” port is lost or locked-out.
  • L-O-X ® valve provides lockable shut-off of air supply, and exhausting of trapped downstream air.
Single Pilot Operated Check Valve Circuit Features

  • Cylinder moves as long as the control valve solenoid is energized. Use for continuous motion or jogging.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if  electrical signal is lost.
Single Pilot Operated Check Valve Circuit Features

  • Cylinder moves as long as the control valve solenoid is energized. Use for continuous motion or jogging.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if electrical signal is lost.
Dual Pilot Operated Check Valve Manual Trapped Pressure Relief Circuit Features

  • Trapped pressure between check valve and cylinder is exhausted when the air supply at the
  • Blowdown Signal Port (BP) is lost or locked-out.
  • Cylinder moves as long as the control valve solenoid is energized. Use for continuous motion or jogging.
  • Cylinder remains stationary if neither control valve solenoid is energized, or if electrical signal is lost.
