Proportional Valves

The valve opening of the proportional directional control valves is controlled in proportion to the input signal and at the proportional directional valve regulated by a position sensor. Proportional directional control valves are suitable for use in control systems and control circuits. Proportional directional valves are available with on board electronics. For proportional directional valves without these electronics, there are different, external control electronics available.

Proportional pressure relief valves control the maximum pressure in the system in proportion to the input signal. Proportional pressure reducing valves control the secondary pressure. Proportional pressure reducing valves and proportional pressure relief valves are available as direct or pilot operated valves. The 2-way pressure compensators and 3-way pressure compensators keep the pressure drop constant and are as sandwich valves equipped with integrated LS change-over valve.
