HSV12-47C Valve
U.S. Patent 8,253,063

HSV12-47C Valve symbol
A solenoid-operated, 4-port, 3-position, direct-acting, spool-type, closed center, screw-in hydraulic cartridge valve for use in high pressure applications.

When de-energized, the HSV12-47C 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. In circuits where work port flows are unequal due to cylinder ratios, the higher return flow should be directed to port 2.
Manual Override Option:The manual override feature is intended for emergency use, not for continuous operation. For normal valve operation (neutral), the manual override pin mus be seated in the center detent groove (ID groove on knob is in-line with top of coil nut). To shift the valve manually from neutral to activate coil S1 function, push the knob down slightly, rotate 90 degrees counterclockwise and pull. To detent in this position, rotate the knob an additional 90 degrees counterclockwise to lock in the upper detent groove. To shift manually from neutral to activate coil S2 function, push the knob down all the way to detent. In this position, rotate the knob ninety degrees clockwise to lock in the lower detent groove.
