VPR3 3/8” - VPR3 1/2” - VPR3 3/4” - VPR3 1”

3 Port Flow Control Valve Ongoing Pressure Line

Use and Operation
This valve enables to keep “P” flow constant to a certain setting, independently of the required pressure or the inlet flow of the valve. Exceeded flow is drained in “B” and it is available for a second use. Also port “B” is insensitive to pressure changes but not to flow changes.

Materials and Features

  • Body: zinc-plated steel - aluminium (VPR3 1)
  • Internal Parts: hardened and ground steel
  • Seals: BUNA N standard
  • Poppet Type: by diameter combination. Minor leakage (few drops per minute)

Connect E to the pressure flow and P to the actuator or to a line of an hydraulic circuit where flow adjustment is needed. Connect B to the tank or to a second actuator. To adjust inlet pressure in P screw in or off hand wheel after loosening the locknut.
