| Solenoid On/Off Valve
Spool-Type Solenoid Valve, Spool 4-Way, 3-Position
QSV08-47D = Reversing valve, 4-Way, 3-Position, Float median Position =
A solenoid-operated, 4-way, 3-position, direct-acting, “motor spool,” screw-in hydraulic cartridge valve.
When de-energized, the QSV08-47D blocks flow to ③, while allowing flow from ② to ①, and from ④ to ①. When coil S1 is energized, flow is allowed from ③ to ④, and from ② to ①. When coil S2 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.
