5 Spools Hydraulic Directional Control Valves
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 5 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.
- Wide choice of hydraulic circuitry and maximum flexibility
- Electrical and mechanical operators can be combined in the same valve
- Spools can be customised with differing metering ranges
- By-pass solenoid valve and manual safety control in order to prevent unauthorised movement of actuators
- Wide range of valve sections with flow control and priority flow control
