Check-Q-meter

Sizes 12 to 32

Up to 350 bar , Up to 560 L/min

  • Installation in manifolds (cartridge valve)
  • With SAE flange ports
  • Sub-plate connection or block, porting pattern to DIN 24340 form D, ISO 5781 and CETOP-RP121 H
  • Check valve pilot operated (leakage-free)
  • The check-Q-meter controls the returning flow QV2 in relation to the flow Qv1 in the inlet port of actuator. For the application in cylinders system, the area ratio (QV2 = QV1 Φ) has to be taken into account
  • Bypass valve, free flow in opposite direction
  • Safety valve, optional (Only for valve with flange port and special plate valve type FD12 and FD16)
