Check valve for water line

Check valves are automatic valves, also known as check valves, one-way valves, return valves or isolation valves.

The water pipe check valve is often used as the bottom valve of the pumping device to prevent the backflow of water. The combination of check valve and globe valve can play the role of safety isolation. The disadvantage is that the resistance is large and the sealing is poor when closed.

According to the structure, the water 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 and horizontal.

◆ Swing check valves are divided into three types: single flap, double flap and multi flap.

◆ The butterfly check valve is a straight-through type.

◆ The connection forms of the above check valves can be divided into four types: threaded connection, flange connection, welding connection and wafer connection.

Flow check valves are versatile and suitable for submersible, drainage, sump pumps and especially for sewage and sludge systems. Common in line check valve water are: KA Series Check Valve, CV Series Check Valve.
