The G77X/77X 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 4 to 57 l/min (1 to 15 gpm) at 210 bar (3000 psi) valve pressure drop per spool land.
The output stage of the valve 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 provided by a cantilevered spring. The valve design is simple and rugged for dependable, long life operation.
These valves are suitable for electrohydraulic position, speed, pressure or force control systems with high dynamic response requirements. The G77X/77X is ideally suited for applications where superior dynamics are a must.
Intrinsically safe valve versions are available for use in applications with potentially hazardous environments. Specific models are certified to FM, ATEX, CSA, TIIS and IECEx standards.
