Directional Valves2-WAY POPPET, WITH INTEGRAL T-8A CONTROL CAVITY,CONTROL PORT 2 TO PORT 1bcLocatingShoulderT-8A21The -8 control option allows the pilot control valve to be incorporated directlyinto the end of the cartridge via the T-8A cavity. These pilot controlcartridges are sold separately and include electro-proportional, solenoid, airpilot, and hydraulic pilot operation.
