PRESSURE CONTROLS
■ Remote Control Relief Valves
This valve is used as a remote control valve for
pilot operated type pressure control valves.
■ Specifications
■ Model Number Designation
■ Instructions
To adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher
pressure or anti-clockwise for lower pressures. After adjustments, do not forget to tighten
the lock nut.
Piping of the tank line should not be connected to any tank line of the other valves, but connected
directly to the tank.
