Stainless steel ball valves can be divided into bypass valves, air valves, pressure relief valves and drain valves according to their different functions. The following is an explanation.
1. Bypass valve: Most ball valves are opened by static water, so set the bypass valve and press it flat first, that is, fill both sides with water.
2. Air valve: When filling with water, it is used to discharge air, and the pontoon closes the valve automatically; when draining, it is used to supplement air, and the pontoon descends on its own.
3. Pressure relief valve: Open and close the valve, discharge the pressure water between the valve and the sealing cover, and avoid wearing the sealing cover.
4. Drainage valve: drains the sewage from the inner and lower parts of the ball housing.
