Posi-Check" Valves; Automatic Dump Valve - SPX Power Team PE55-E110 Series Operating Instructions Manual

4. "Posi-Check" Valves

If an open center valve is used, a hydraulic gauge in the gauge port shows zero pressure when the valve
is switched to the neutral (hold) position. Cylinder pressure, however, is held without loss. If reading the
cylinder pressure, a gauge must be installed in the outlet port of the valve.
To install a hydraulic gauge (refer to Figure 4):
A. Remove the pipe plug from the valve's gauge port.
B. Install a steel 45° elbow fitting.
C. Install the gauge into the 45° elbow fitting.

5. Automatic Dump Valve

A. Activate the pump unit to advance the cylinder.
B. Release the remote switch to release pressure and retract the cylinder.
Never use this valve for lifting a load!
