YK43X/F gas pressure reducing valve

Pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the outlet pressure change, and the pilot valve is opened and closed to drive the piston to adjust the flow area of the throttle part of the main valve, so as to realize the function of pressure reduction and stabilization. This product is mainly used in gas pipeline, such as air pressure reducing valve, nitrogen pressure reducing valve, oxygen pressure reducing valve, hydrogen pressure reducing valve, liquefied gas pressure reducing valve, natural gas and other gases.

Pressure regulating steps of pressure reducing valve:
1. Close the gate valve in front of the pressure reducing valve, open the gate valve behind the pressure reducing valve, create downstream low pressure environment, rotate the adjusting screw counterclockwise to the top position (relative to the lowest outlet pressure), and then close the gate valve behind the pressure reducing valve.
2. Slowly open the gate valve in front of the pressure reducing valve to full open.
3. Slowly turn the adjusting screw clockwise to adjust the outlet pressure to the required pressure (subject to the gauge pressure behind the valve); After adjustment, lock the lock.
4. Lock the nut and open the back gate valve of the pressure reducing valve.
5. If the outlet pressure is higher than the set pressure, it must be readjusted from the first step, that is, it can only be adjusted from low pressure to high pressure.
