Directional Spool Valves

This range of proportional valves is used to provide load-independent speed control of motors and cylinders.

This range of proportional valves is used to provide load-independent speed control of motors and cylinders.

These low-weight (aluminium) seat valve blocks are used to control single- or double acting cylinders. They are applied where high levels of leaktightness are required. The design uses a solenoid operated, direct acting, 2/2 bi-directional seat valve. They close the flow path to or from hydraulic actuators with virtually zero leakage.

Series HDS directional control valves represents a flexible unit construction, the elements of which may be combined into one valve unit as required.

They are available in 8 different sizes, and with parallel, serial, serial/parallel,  Load Sensing and Flow Sharing circuitry. In addition, the range includes inlet and intermediate flow control sections with either manual or electro-proportional operators. Where accurate control of speed and actuator position is needed, the valves satisfy the most complex hydraulic circuit requirements.
