Servo cartridge NG-80 with safety function

The 2-way servo cartridge valves can be used for flow or pressure control. The required electronics for signal processing and the controller are completely integrated into the valve. The setpoint specification can be fed into the valve via an analog signal or via a fieldbus interface.
The SC80 valves are equipped with a magnetostrictive displacement transducer. A secondary displacement encoder (LVDT) is located in the control valve. Due to the external control ports Z and W, the closing function of these valves is redundant. If the external control pressure is correctly designed, the safety spool can override the control valve at any time to close the valve.
The built-in valve version for mounting in hydraulic blocks is ideally suited for high flow rates with minimal pressure loss.
