Correct pressure regulation steps for Wear-resistant Ball Valve

1. What is a Wear-Resistant Ball Valve?

A Wear-resistant Ball Valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure.

2. Pressure regulation steps for Wear-resistant Ball Valve:
1) Close the Gate Valve in front of the Wear-resistant Ball Valve, open the gate valve behind the Wear-resistant Ball Valve, and create a low-pressure environment downstream;
2) Turn the adjusting screw counterclockwise to the upper position (relatively low outlet pressure), and then close the gate valve behind the Wear-resistant Ball Valve;
3) Slowly open the gate valve in front of the Wear-resistant Ball Valve to full open;
4) Slowly rotate the adjusting screw clockwise to adjust the outlet pressure to the required pressure (based on the gauge pressure behind the valve); after adjustment, tighten the locking nut and open the gate valve behind the Pressure Reducing Valve;
5) If the outlet pressure is higher than the set pressure during adjustment, it must be readjusted from the first step, that is, it can only be adjusted from low pressure to high pressure.
