How to adjust the TESCOM pressure reducing valve regulator 44-2263

There are several steps to adjust the size of the pressure reducing valve:

Step 1: Close the gate valve in front of the pressure reducing valve, open the gate valve behind the pressure reducing valve, and create a downstream low-pressure environment;

Step 2: Rotate the adjustment screw counterclockwise to the highest position (relative to the lowest outlet pressure), and then close the pressure reducing valve and gate valve;

Step 3: Slowly open the gate valve in front of the pressure reducing valve until it is fully open;

Step 4: Slowly rotate the adjustment screw clockwise to adjust the outlet pressure to the required pressure (based on the gauge pressure behind the valve);

Step 5: After adjustment, tighten the nut and open the pressure reducing valve and gate valve;

Note: Due to the working principle of the pressure reducing valve, 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.
