HSP12-47C Valve

SYMBOL:HSP12-47C Valve symbol


A high pressure, proportional, 4 port, 3 position, spool type, screw-in, cartridge style,
hydraulic solenoid valve.

When de-energized, the HSP12-47C blocks all ports. When the S1 coil is energized,
flow is allowed from port 3 to 4 and from 2 to 1. When the S2 coil is energized, flow is
allowed from port 3 to 2 and 4 to 1. In circuits where work port flows are unequal due
to cylinder ratios, the higher return flow should be directed to port 4.
Manual Override Option: The manual override feature is intended for emergency use,
not continuous operation. For normal valve operation (neutral) the manual override pin
must 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 the S1 coil, push the knob down slightly,
rotate 90 degrees counterclockwise, then pull. To detent in this position, rotate the knob an
additional 90 degrees counterclockwise to lock in the upper detent groove. To shift manually
to activate the S2 coil, push the knob down all the way. To detent in this position, rotate the
knob 90 degrees clockwise to lock in the lower detent groove.
