Use and Operation

These valves are used to control actuator’s movements and block in one direction in order to enable the following functions:

  • under control descent of a load: load’s weight doesn’t carry it away, as the valve prevents any cavitations of the actuator
  • limited maximum pressure in the case of shocks created by loads, overloads or sudden manoeuvrings (load control with opened centre distributor).

Direct flange is ideal for Danfoss engine type OMS and provides a maximum safety, very low pressure drops and solid installation.

Materials and Features

  • Body: zinc-plated steel
  • Internal Parts: hardened and ground steel
  • Seals: BUNA N standard
  • Poppet Type:  minor leakage
  • Standard Setting: 320 Bar Valve setting must be at least 1,3 times more than load pressure in order to enable the valve to close even when undergone to maximum load pressure.


Connect V1 and V2 to the pressure flow, C1 to the free flow side of the actuator and flange C2 to the motor’s side you want the flow to be blocked.



  • Direct Mount OMS Series Motor
