DASV08-47A Spool, 4-Way, 3-Position, Tandem Center

DESCRIPTION

A solenoid-operated, four-way, three-position, direct-acting, spool-type, tandem center, screw-in hydraulic cartridge valve.

OPERATION

When de-energized，DASV08-47A blocks cylinder ports, while allowing flow from 3 to 1 . When coil 1(S1) is energized, flow is allowed from 3 to 2 , and from 4 to 1 . When coil 2 (S2) is energized, flow is allowed from 3 to 4, and from 2 to 1.In circuits where work port flows are unequal due to cylinder ratios, the higher return flow should be directed to port 2 .While 1 may be fully pressurized, it is not intended for use as the valve’s inlet. Operation of Manual Override Option: To override, push the knurled knob to activate the coil 2 (S2) function; pull the knob to activate the coil 1 (S1) function.
