QSP08-47C

DESCRIPTION:
A solenoid-operated, 4-way, 3-position, spool-type, closed center, screw-in hydraulic cartridge valve.
When de-energized, the QSP08-47C blocks 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.Initial meter-in flow begins at a nominal 0.4 amp on a 12 VDC system. Full flow of 11 lpm (3 gpm) occurs at 1.0 to 1.1 amp on a 12 VDC system. While ① may be fully pressurized, it is not intended for use as the valve’s inlet. In circuits where work port flows are unequal due to cylinder ratios, the higher return flow should be directed to port ②.
