| Solenoid On/Off Valve
Spool-Type Solenoid Valve, Spool 4-Way, 3-Position
QSV08-47C = Reversing valve, 4-Way, 3-Position, Median Closed position =
A solenoid-operated, 4-way, 3-position, direct-acting, spool-type, closed center, screw-in hydraulic cartridge valve.
When de-energized, the QSV08-47C blocks flow to ③, but allows flow from ②to①，or from④to①。 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. While 1 may be fully pressurized, it is not intended for use as the valve’s inlet..
