Check Valve

A check valve is a valve used to prevent the backflow of the medium in the pipeline or equipment. Check valves are automatic valves, also known as no-return valves, or one-way valves. The check valve is often used as the bottom valve of the pumping device, which can prevent the backflow of water.

Check valves used in combination with the globe valve, can play the role of safety isolation. The disadvantage is that the resistance is large and the sealing performance is poor when closed.

According to the structure, check valves can be divided into three types: lift check valve, swing check valve and butterfly check valve:
* There are two types of lift check valves: vertical check valve and horizontal check valve.
* The swing check valve is divided into three types: single-clack valve, double-clack valve and multi-clack valve.
* The butterfly check valve is a straight-through type.

The above types of check valves can be divided into four types according to the connection form: threaded connection, flange connection, welded connection and wafer connection.
