A check valve is a valve in which the opening and closing member is a circular valve flap and acts on its own weight and medium pressure to block the flow of the medium. It is an automatic valve, also known as a check valve, check valve, return valve or isolation valve. The flap motion mode is divided into lift type and swing type. The lift check valve is similar in construction to the shut-off valve and lacks only the valve stem that drives the flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side).

 

The selection criteria for the check valve are as follows:

1. The check valve should determine the corresponding size, the valve supplier must provide the data of the selected size, so that you can find the valve size when the valve is fully open at a given flow rate;

2. For high and medium pressure check valves below DN50mm, vertical lift check valves and straight lift check valves should be used;

3. For low-pressure check valves below DN50mm, butterfly check valves, vertical lift check valves and diaphragm check valves should be used;

4. For high and medium pressure check valves with DN greater than 50mm and less than 600mm, a swing check valve should be used;

5. For medium and low pressure check valves with DN greater than 200mm and less than 1200mm, wear-free ball check valves should be used.
