Sectional Directional Valve Series HDS30
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.
