WebJul 14, 2024 · As indicated in the diagram below, one direct-controlled directional control valve, also known as a pilot valve, uses a solenoid as an actuation element. Solenoids operate the primary valves, which in turn control the 3/2 and 4/2 directional control valves. As a result, these valves are known as pilot valves, whereas the regulated valve is ... WebSymbol Description SVRV10-26X is a normally open, solenoid operated, spool type, screw in relief valve. When the coil is activated, the pilot closes the drain flow and the spool closes port 2. In this position, the valve works as a relief valve, relieving flow from port 1 to port 2. The pilot opens when the pressure at port 1 exceeds the set ...
