DIN Swing Check valves
The closure member open and close automatically depends on the flowing of medium and power to prevent refluence of medium is called check valve.
Check valve is a kind of automatic valves. It is mainly used for pipe line which only allows one-way medium to avoid accident. Based on structure, check valve can be classified into lift check valve, swing check valve and butterfly check valve.
