　　▲Remote Control Relief Valves. This valve is used as a remote control valve for pilot operated type
pressure control valves.
 

　　▲To adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher pressures 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 reservoir.
 

　　▲Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar is equivalent to 10 MPa (1450 PSI).
 

　　▲If the internal volume of the vent line is too large, chattering is likely to occur.
