3-Way Pressure Controlled Servo Valve

three-way pressure-controlled servo valve, part 101125

The Three-Way High Flow single stage pressure compensated servo valve delivers a precise cylinder pressure as a function of torque motor current. The Three-way Pressure Controlled Servo Valve is designed to operate on turbine oil, hydraulic fluid, diesel oil, jet fuel or stoddard solvent. The Three-Way Servo Valve operation offers pressure feedback from cylinder port and permanent magnet and dry coil motor torque. The Three Way Servo has low hysteresis and threshold with low electrical power consumption.
