How to adjust the pressure of liquefied gas pressure reducing valve

Turn the plastic bolt with a flat screwdriver to adjust. The method to adjust the pressure of the pressure reducing valve for liquefied gas is to unscrew the plastic cover on the pressure reducing valve, and the plastic bolt can be screwed with a screwdriver. If tightened clockwise, the output of the pressure reducing valve will be very small and the gas pressure will be very low. If the bolt is loosened counterclockwise, the output of the pressure reducing valve will be great and the gas pressure will be high. When the pressure sensor detects that the valve pressure indicates an increase, the valve opening of the pressure reducing valve decreases; When the pressure drop after the pressure reducing valve is detected, the valve opening of the pressure reducing valve is increased to meet the control requirements.
