Hydraulic directional control valve SDRA series

Series SDRA--4 units are stack mounting valves which provide a 3--way pressure reducing function in the P, A or B lines. The reduced pressure on the secondary side (P1) is held constant regardless of higher fluctuations in the primary side (P). If external forces cause the secondary pressure to rise above the valve setting, the 3--way reducing valve then begins to function as a secondary relief valve. The ∅ 3 mm location pin on the actuator face of the valve prevents incorrect mounting. Valves are shipped as standard with screw adjustment. Alternatively, they can be supplied with adjustment by hand knob, or lockable hand knob.
