DASV08-47B Spool, 4-Way, 3-Position, Open Center

DESCRIPTION

A solenoid-operated, 4-way, 3-position, direct-acting, spool-type, open center, screw-in hydraulic cartridge valve.

OPERATION

When de-energized，DASV08-47B allows flow to all ports. When coil #1 is energized,flow is allowed from 3 to 4 , and from 2 to 1 . When coil #2 is energized, flow is allowed from 3 to 2 , and from 4 to 1 . In circuits where work port flows are unequal due to cylinder ratios, the higher return flow should be directed to port 2 . NOTE: 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 button to activate the coil #2 (S2) function, or pull the knob to activate the coil #1 (S1) function.
