Proportional directional spool valve types PSL and PSV

The proportional directional spool valve type PSL is suitable for constant pump systems, while type PSV is suitable for control pump systems with a pressure/flow controller. The flow rates and load pressures for the individual consumers can be individually adjusted. The proportional directional spool valve types PSL and PSV can be adapted to various control tasks, e.g. for safety functions.


Technical data

  • Pmax: 400 bar
  • Qmax. consumer: 240 lpm
  • Qpu max: 300 lpm

Proportional directional spool valve types PSLF, PSVF and SLFV

The proportional directional spool valve type PSLF is suitable for constant pump systems, while type PSVF is suitable for control pump systems with a pressure/flow controller. The proportional directional spool valve types PSLF and PSVF are available as individual manifold mounting valves in valve banks. The flow rates and load pressures for the individual consumers can be individually adjusted.

Technical data

  • Pmax: 400 bar
  • Qmax. consumer: 400 lpm
  • Qpu max: 1000 lpm

Proportional directional spool valve type EDL

The directional spool valve type EDL with series connection is actuated directly. The flow rates for the individual consumers can be individually adjusted. The proportional directional spool valve can be flexibly adapted to different control tasks by means of additional functions in the intermediate plates and ancillary blocks.

 

Technical data

  • Pmax: 320 bar
  • Qcons. Max: 48 lpm
  • Qpu max: 100 lpm

Directional spool valves type CWS

The directional spool valve bank type CWS with series connection is actuated directly. The consumers are black/white controlled. A range of connection blocks and mounted blocks offer a wide range of applications. The valve bank CWS is used mainly in mobile hydraulics. In stationary hydraulics, the direct mounting on the compact hydraulic power pack results in an extremely compact system solution.


Technical data

  • Pmax: 315 bar
  • Qmax: 40 lpm

Load-holding valve type CLHV

The load-holding valve type CLHV is suitable for applications with low and medium tendencies to oscillate and is used especially in connection with proportional directional spool valves, e.g. types PSL and PSV. It is also available with return pressure compensation and spring chamber relief.

 


Technical data

  • Pmax: 350 bar
  • Qmax: 320 lpm

Load-holding valve type LHDV

The load-holding valve type LHDV has special damping characteristics. It is suitable for applications that are highly prone to oscillations, and is used especially in connection with proportional directional spool valves, e.g. types PSL and PSV. When the valve is closed, it is completely tight and prevents all leaks. Shock valves and shuttle valves with or without restrictor check valves can be fitted in the load-holding valves, e.g. to relieve hydraulic brakes with a delay.

Technical data

  • Pmax: 420 bar
  • Qmax: 80 lpm
