Moog 72 Series Flow Control Servo Valves PRODUCT OVERVIEW The 72 Series flow control servo valves are throttle valves for 3 and preferably 4-way applications. They are a high performance, 2-stage design that covers the range of rated flows from 95 to 225 l/min (25 to 60 gpm) at 35 bar (500 psi) valve pressure drop per spool land. The output stage is a closed center, four-way sliding spool. The pilot stage is a symmetrical double-nozzle and flapper, driven by a double air gap, dry torque motor. Mechanical feedback of spool position is pro­vid­ d by a e cantilever spring. The valve design is...

Moog 72 Series Flow Control Servo Valves DESCRIPTION OF OPERATION The 72 Series Flow Control Servo Valve consists of a polarized electrical torque motor and two stages of hydraulic power amplification. The motor armature extends into the air gaps of the magnetic flux circuit and is supported in this position by a flexure tube. The flexure tube acts as a seal between the electromagnetic and hydraulic sections of the valve. The 2 motor coils surround the armature, one on each side of the flexure tube. The second stage is a conventional four-way spool design in which output flow from the...

TECHNICAL DATA Moog 72 Series Flow Control Servo Valves ELECTRICAL DATA Rated current and coil resistance A variety of coils are available for 72 Series Servo Valves, which offer a wide choice of rated currents. ­ Coil impedance Inductance is determined under pressurized operating conditions and is greatly influenced by back electromagnetic forces of the torque motor. These effects vary with most operating conditions, and vary greatly with signal frequencies above 100Hz. The apparent coil inductance values given are determined at 50 Hz. The resistance and inductance of standard coils are...

Moog 72 Series Flow Control Servo Valves NULL FLOW ADJUSTMENT It is often desirable to adjust the null flow of a servo valve independently of other system parameters. We provide two means to accomplish this; using a mechanical adjustment on the side of the valve body or an (optional) magnetic adjustment on the top of the torque motor cover. Valves with mechanical null adjustment allow for at least ±10% adjustment of null flow. The mechanical null adjustment is an eccentric bushing retainer pin, located above the tank port designation on the valve body, which if rotated provides control of...
