  • DIRECT ACTING PRESSURE REDUCING VALVE WITH CHECK VALVE

    TYPE: VRPRL

    Use and Operation
    This valve allows to preserve constant the pressure downstream, regardless of the upstream pressure. The check valve allows the free return of the oil.

    Materials and Features

    • Body: zinc-plated steel
    • Internal Parts: hardened and ground steel
    • Seals: BUNA N standard
    • Poppet Type:  70 cc/min (350 Bar to port P)

    Applications
    Connect P to the main circuit, the port Reg. to the circuit where you want to reduce pressure and port T to the tank.

  • SEQUENCE VALVE

    TYPE: VSQAPP

    Use and Operation
    Sequence valve is used to feed 2 cylinders in sequence: it provides flow to the secondary circuit when a primary circuit function has been completed reaching the pressure setting. Return flow is free. Being insensitive to back pressures, it allows to use the circuit pressure to control both the actuators.

    Materials and Features

    • Body: zinc-plated steel
    • Internal Parts: hardened and ground steel
    • Seals: BUNA N standard
    • Poppet Type:  minor leakage

    Applications
    For use with 2 actuators, follow the mounting instructions indicated in the scheme.For different uses, mount the valve keeping into consideration that, when the valve reaches the setting pressure, the flow goes from V towards C, whilst flow is free from C to V.

  • DUAL CROSS RELIEF VALVE FLANGABLE ON DANFOSS MOTORS OMP/OMR

    TYPE: VAU OMP/OMR

    Use and Operation
    Made up by 2 relief valves with crossed tank, this valve is used to block pressure to a certain setting in the 2 ports of an actuator/hydraulic motor. It’s ideal to provide protection against sudden shock pressures and to adjust different pressures in the 2 ports of an hydraulic circuit as well. Direct flange is ideal for Danfoss motors type OMP-OMR  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

    Applications
    Flange M1 and M2 directly to the motor and connect ports V1 and V2 to pressure flow.

  • DUAL CROSS RELIEF VALVE

    TYPE: VAU

    Use and Operation
    Made up by 2 relief valves with crossed tank, this valve is used to block pressure to a certain setting in the 2 ports of an actuator/hydraulic motor. It’s ideal to provide protection against sudden shock pressures and to adjust different pressures in the 2 ports of an hydraulic circuit as well.

    Materials and Features

    • Body: zinc-plated steel
    • Internal Parts: hardened and ground steel
    • Seals: BUNA N standard
    • Poppet Type:  minor leakage

    Applications
    Connect V1 and V2 to the pressure flow or to the actuator/hydraulic motor. Vice versa for the remaining ports V1 and V2. Mounting by the actuator is highly recommended in order to avoid pressure drops.

  • RELIEF VALVE

    VMP

    Use and Operation
    The relief valve provides overload protection in a fast and accurate way: when it reaches pressure setting, the valve open allowing pressure relief in order not to exceed this setting.

    Materials and Features

    • Body: zinc-plated steel
    • Internal Parts: hardened and ground steel
    • Seals: BUNA N standard
    • Poppet Type:  minor leakage

    Applications
    Connect circuit port with pressure to P and tank port to T. Port P is reversible..

  • OVERCENTRE VALVES FLANGABLE ON DANFOSS MOTORS OMP/OMR

    TYPE: VBCDF 

    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 OMP-OMR 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 BarValve 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.

    Applications
    Connect V1 and V2 to the pressure flow and flange C1 and C2 directly to the engine.

  • DOUBLE OVERCENTRE VALVE

    TYPE: VBCD 

    Use and Operation
    These valves are used to control actuator’s movements and block in both directions in order to have a under control descent of a load; load’s weight doesn’t carry it away, as the valve prevents any cavitations of the actuator.

    Materials and Features

    • Body: zinc-plated steel
    • Internal Parts: hardened and ground steel
    • Seals: BUNA N standard
    • Poppet Type:  minor leakage

    Applications
    Connect V1 and V2 to the pressure flow, C1 and C2 to the actuator to be controlled. In-line mounting.

  • SINGLE PILOT OPERATED CHECK VALVE

    TYPE: VBPSE

    Use and Operation
    These valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in the reverse direction until pilot pressure is applied.

    Materials and Features

    • Body: zinc-plated steel
    • Internal Parts: hardened and ground steel
    • Seals: BUNA N standard
    • Poppet Type:  any leakage

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