How is the pressure change in the air-cooled tower? Generally, changes in the pressure of the air-cooled tower affect the flow rate of the normal-temperature water as well as the amount of water returning to the air-cooled tower; consequently, the return water valves will fluctuate. However, with proper PID tuning, such large fluctuations do not occur. As for whether the valves operate on a pneumatic open or pneumatic close principle, this has little impact~~

Please adjust the valve PID as soon as possible~~ The air-cooling return water valve is a very important one~~
How long have you been using your valves? Remember to check them regularly. There’s also a check valve at the back to prevent jamming
Yes, a failed check valve is terrifying when the machine stops running – it can cause water to fill the air-cooling tower, and in severe cases, the water can even flow back into the air compressor and the molecular sieve~~
