Single Stage PCU Servo Valve Description
The high flow single stage servo valve is manufactured in
a number of configurations. Its inherent pressure balance
results in low electrical power consumption (1.0 watt maximum).
The servo valve is capable of operating with jet fuels, stoddard
solvent, red oil, turbine oil, air and natural gas.
