Pilot Proportional Cartridge Valve – 2 Stage
The “analog proportional pressure control valve” is an electro-hydraulic unit designed to modulate pressure from 0 to 30 bar (0 to 435 PSI). Flows of FEMA’s 2 stage cartridge valves range from .5 l/s to 3.75 l/s at 20 bar delta (8 to 60 GPM @290 PSID). Other pressures, gain curves, and reverse gain are available.
This two-stage unit features high spool driving forces which enable it to overcome heavy contamination and debris. This valve can operate at contamination levels of ISO 25/23 intermittently, and ISO 19/16 continuously. As shown in the schematic, this is a two position, normally closed, three-way pressure control valve, and is designed for applications such as clutch control within power shift transmissions. It is also used on other various applications within the off-road mobile market.
