EM 21 (D, DS)
2/2 Way Ball Seated Directional Screw-in Seated Valve EM 21 (D, DS)
These 2/2-way ball seated directional valves are either directly or pilot actuated by a solenoid. With the directly actuated version the valve passage is opened or closed by a cone whereas with the piloted a piloting duct of a stepped piston is opened or closed generating a pressure difference at the opposing facial areas of the piston forcing it in the openor closed position. Type EMP is a proportional valve, acting like a throttle but with zero leakage in blocked position. The dampened version will increase the switching time for on/off controls (hydraulic ramp). The wet armature solenoids for the valve actuation are pressure resistant, where all moving internalparts are flushed by oil. There is a wide range of connection blocks either for pipe connection orfor banjo bolt mounting, which may feature optional elements such as drain valve, bypass throttle, pressure switch, 2-way flow control valve etc.
