Reducing/Relieving Valves, Electro-ProportionalPILOT OPERATED, MAIN STAGE WITH INTEGRAL T-8A CONTROL CAVITY,DRAIN TO PORT 4, EXTERNALLY DRAINEDbT-8A CavityT-8ACav34The -8 control option allows a pilot control valve to be incorporated directlyinto the end of the modulating element via the T-8A cavity. These pilot controlcartridges are sold separately and include electro-proportional, solenoid, airpilot, and hydraulic pilot operation.
