Key Features and Advantages
The G772K240A S38FOFA4V14 redefines precision flow control with Moog’s patented Direct Drive technology, eliminating pilot stages for 60% faster response compared to conventional servo valves. Its symmetrical spool design achieves 0.02% repeatability in high-cycle applications like injection molding machines. Advanced contamination tolerance (ISO 17/14/11) ensures reliable operation in particle-laden hydraulic systems without performance degradation.
Energy-efficient operation: Low null leakage reduces power consumption by 35% in standby modes. The valve’s integrated LVDT feedback provides real-time spool position monitoring (±0.1μm resolution) for closed-loop control systems. Optional S38FOFA4V14 configuration includes hardened chrome plating for water-glycol fluid compatibility in marine applications.

Application Areas
In steel rolling mills, the G772K240A S38FOFA4V14 controls hydraulic gap adjustment systems with 0.01mm positional accuracy under 3000-ton loads. Aerospace testing rigs utilize its -40°C cold-start capability for actuator fatigue testing. Plastic injection machines benefit from the valve’s 500Hz frequency response for precise melt-pressure control during thin-wall molding.
Offshore applications deploy this valve in dynamic positioning thrusters, where its seawater-resistant coating withstands ISO 12944 C5-M marine environments. The CANopen interface option enables seamless integration with modern press brake controllers for metal forming operations requiring 0.1° bend angle precision.

Installation and Maintenance
Installation preparation: Flush hydraulic lines to achieve ISO 16/13/10 cleanliness before installing the G772K240A S38FOFA4V14. Use torque-limiting wrenches (35-40 Nm) for port connections to prevent body distortion. Align mounting surface within 0.05mm/m to avoid mechanical stress.
Maintenance recommendations: Replace inlet filters every 2,000 operational hours. Perform null calibration quarterly using Moog ValveCheck software. Monitor LVDT feedback signals monthly – deviations >5% indicate wear inspection required. For water-glycol applications, flush system annually with inhibitor-enriched fluid.
Product Assurance
Every G772K240A S38FOFA4V14 undergoes 500-hour accelerated life testing including 1 million full-stroke cycles. Moog’s FieldCare program provides 24/7 technical support with guaranteed 48-hour response for critical failures. The 3-year warranty covers all wear parts except filters, extendable through certified maintenance plans. Lifetime access to Performance Analytics Portal enables predictive maintenance scheduling based on actual operating data.
