S-020 HC / S-022 HC / S-024 HC High Capacity Automatic Air Release Valve
Brand: A.R.I. Flow Control AccessoriesThe S-020/2/4 HC automatic air release valve discharges accumulated air/gas from the system while it is operating under pressure.
The presence of air/gas in the system can reduce the effective cross sectional flow area, resulting in increased pressure loss and deceased flow. Unwanted air/gas may also cause water hammer and metering inaccuracies, while hastening corrosion.
The S-020/2/4 HC automatic air release valve builds an air/gas pocket inside the valve body, separating the liquid with its solid particles from the sealing mechanism, ensuring a leak-free seal.
