Advantages
- 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
