Product Introduction: It belongs to the G77x series of servo valves, adopting a 2-stage design. The output stage is a closed-center, four-way sliding spool, and the pilot stage is a symmetrical double-nozzle and flapper driven by a double air gap, dry torque motor. The spool position is mechanically fed back through a cantilever spring, featuring a simple and robust structure that can achieve reliable and long-term operation.
Technical Specifications: The rated flow rate ranges from 4 to 57 L/min at a valve pressure drop of 210 bar. It has high resolution, with a hysteresis of less than a certain low percentage. The valve has a small body size and lightweight design.
Functional Features: It uses low-friction, double-nozzle pilot stage technology, enabling high dynamics, high resolution, and low hysteresis. The high spool driving force and robust design ensure long service life. Intrinsically safe versions are available, which can be used in potentially hazardous environments and meet standards such as FM, ATEX, CSA, TL5, and Ecex. When the electrical signal is lost, the valve can automatically return to the zero position to achieve a fail-safe function. The symmetrical structure ensures maximum stability under various conditions and is compatible with many different fluids.
Application Scenarios: Suitable for electro-hydraulic position, speed, pressure, or force control systems that require high dynamic response, such as in the fields of industrial machinery, aerospace, and metallurgy, especially in occasions with strict control accuracy requirements and potentially hazardous environments.
