Set the desired pressure...

After correctly installing/connecting the valve, engage auxiliary hydraulics
on the parent machine observing all safety precautions.
1. Observe PSI reading on ‘[ P ]’ Gauge.
2. To Increase the pressure setting turn the adjustment screw on the cartridge
    valve in a clockwise direction until desired pressure setting is obtained.
3. To Decrease pressure setting turn the adjustment screw on the cartridge valve
    in a counter-clockwise direction until desired pressure setting is obtained.

Monitoring torque...

The Inline Pressure Relief Valve can be used in conjunction with either Digga Torque
Logic or Differential Pressure Gauge to obtain accurate torque measurements while
controlling the torque the drive unit is capable of transmitting through the pile.
The Differential Pressure Gauge displays the hydraulic pressure being applied through the drive 
unit, which can then be reference back to a torque chart to give a theroretical torque measurement.
The Digga Torque Logic monitoring system will provide accurate torque readings of up to 98%
accuracy. This system also has the ability to be able to data log the results of each pile installation.

EASY TO INSTALL

Connecting to the machine / power source

1. Connect the pressure hose from the machine that will rotate the shaft
    of the drive unit clockwise to the port marked ‘[ P ] In’.
2. Connect the machine return line hose to the port marked ‘[ T ] Out’.
3. Connect the port marked ‘[ P ] Out’ to the pressure side of the motor.
4. Connect the port marked ‘[ T ] In’ to the return side of the motor.

Attach the Gauges directly to the ¼” NPT Ports on the face of the valve.
