Proportional directional spool valves are a type of directional valve. They control the direction of movement and the velocity of individual or multiple hydraulic consumers actuated simultaneously.

Control is independent of the load and continuous. It is possible to operate several actuators simultaneously and independently of each other at different speeds and pressures until the sum of the flows through all actuators reaches the maximum flow rate of the pump output.

The proportional directional spool valve type JYPSL is suitable for constant pump systems and type JYPSV is for variable pump systems. The flow rates and load pressures for the individual consumers can be individually adjusted.
