Pilot Operated Solenoid Valves

FEMA Corporation’s high-frequency pilot operated hydraulic solenoid valves are frictionless hydraulic pressure modulation valves that operate with direct-current or a simple >1000 Hz high-frequency electrical input. Our two-stage cartridge valves feature E-H pilot proportional pressure control to modulate pressure from 0 to 30 bar, and flow range near 4 liters per second at 20 bar delta. The two stages provide high-spool driving force, and our advanced manufacturing process for the piloted design maintains efficiency in heavily contaminated systems. FEMA’s high-frequency valves, often used in transmission clutch and PTO control, offer high reliability, low cost and proportionality while maintaining a small size and weight.
