SOLENOID PROPORTIONAL VALVE POPPET, 3 PORT, NORMALLY CLOSED U.S. PATENT # 7,921,880
A solenoid-operated, 3 port, normally closed, poppet-type, proportional, screw-in hydraulic cartridge valve, designed for low leakage, blocking and load-holding applications. When energized, the poppet lifts to allow flow from port 3 to ports 1 and 2, flow at port 2 is typical for load sensing applications but does not include a check valve for isolation.
