Directional spool valves are a type of directional valve. They control the direction of movement and the velocity of single and double-acting hydraulic consumers. The range includes on/off directional spool valves, proportional directional spool valves and valve combinations.
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.

Qmax. consumer: 240 lpm
Qpu max: 300 lpm
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.

The proportional directional spool valve type MICK is a combination of the proportional directional spool valve type PSL and specially designed 8/3-way diverter valves which are flanged-mounted on the PSL sections. The PSL sections proportionally control the flow rate and the downstream diverter valves distribute it to the individual consumers. Up to three dual-acting consumers can thus be supplied with one valve section.

Load-holding valves are a type of pressure control valve. They prevent loads on cylinders or motors dropping in an uncontrolled manner. For this purpose they are pre-loaded with a pressure setting that is higher than the largest possible load. A hydraulic piston controls the opening of the valve to achieve the required lowering velocity.
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.
Pmax: 350 bar
Qmax: 320 lpm
The type OSCA-D load-holding valve is especially suitable for applications that are either particularly susceptible to vibration or that work with very high load pressures. The valve is designed as a screw-in valve and is easy to install and remove. Choose from a range of connection blocks. Matching tools for producing your own blocks are available.
Pmax: 500 bar
Qmax: 40 lpm
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.
Pmax: 420 bar
Qmax: 80 lpm
Load-holding valves are a type of pressure control valve. They prevent loads on cylinders or motors dropping in an uncontrolled manner. For this purpose they are pre-loaded with a pressure setting that is higher than the largest possible load. A hydraulic piston controls the opening of the valve to achieve the required lowering velocity.
