HAWE GR 2-4 R-G24 DIRECTIONAL SEATED VALVE P/N 7000 4103-00

Directional control valves are generally used for the direct, leakage free control of consumers and as pilot valves for hydraulically actuated valves (depending on the flow pattern). They are designed as spring returned ball seated valves. The valve elements are forced into their respective switching position against the spring force and fluid pressure by various actuation elements via an elbow lever acting on a pin. A strainer insert in the inlet port prevents the entry of coarse contamination. The fluid ducts end as holes with O-ring seals at the ground, bottom surface of the valve body. Pipes may be connected either via customer furnished connection blocks or sub-plates (for individual valves with sub-plates see sect. 5 or for valve banks see D 7302). These valves do not show any leakage in blocked switching position. Reliable shifting is ensured, as these valves are designed as ball seated valves where there is no seizing or sticking in working position under full pressure. The leverage between actuation and valve element ensures low actuation forces and smooth shifting. To avoid interaction, most of these directional control valves are available with check valve inserts and return pressure stops or orifice inserts to limit the inflow of oil. Individual valves with sub-plate, enabling direct pipe connection, may be equipped with a by-pass check valve, a pressure limiting valve, or a rectifier circuit by means of check valves.
