How to adjust the size of vehicle natural gas pressure reducing valve

1. First, the pre-tightening pressure of the spring can be changed by adjusting the adjusting screw, and the changed pressure value needs to be confirmed by pressure test.

2. Then adjust the outlet pressure counterclockwise, stop after changing 0.2 MPa, and increase 0.2 MPa when adjusting clockwise.

3. Secondly, it is necessary to confirm whether the outlet pressure is within the required range after adjustment. If not, we must continue to adjust.

4. After the function is finally confirmed to be normal, the adjustment of the natural gas pressure reducing valve is completed.
