| Solenoid On/Off Valve
Spool-Type Solenoid Valve, Spool 4-Way, 3-Position
QSV10-47A = Reversing valve, 4-Way, 3-Position, Series connection median position =
A solenoid-operated, 4-way, 3-position, direct-acting, spool-type, tandem center, screw-in hydraulic cartridge valve.
When de-energized, the QSV10-47A blocks cylinder ports, while allowing flow from ③ to ①. When coil S1 is energized, flow is allowed from ③ to ②, and from ④ to ①. When coil 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.
