Product information

Up to 3.8 lpm

Direct Acting Proportional, Pressure Reducing/Relieving valve, Slip-in Type.

Operation

The D-IPDAR43C generates a variable pressure in response to a PWM (Pulse Width Modulated) current signal. With no current applied to the proportional solenoid, the inlet port 2 is blocked and the regulated port 3 is vented to port 1. As current is increased, fluid pressure is proportionally controlled at the regulated port 3. On attainment of proportionally determined pressure at 3, the cartridge shifts to block flow at 2, thereby regulating pressure at 3. In this mode, the valve also will relieve 3 to 1 at a variable value over the set reducing pressure.

This works with an external driver.

Notes

  • Inlet pressure 350 bar available on request.
  • Valve is not supplied with a body, but bodies are available on request.
  • PWM driver is available on request.
