Plastic Check Valve, also known as plastic one-way valve, is a kind of valve opened and closed by relying on the pressure of the medium itself, without manual switch. Plastic Check Valve is divided into Swing Check Valve and ball core check valve according to the structure. The connection methods are flange type, wafer type, socket welding type, etc.

Plastic Check Valve, also known as plastic one-way valve, is a kind of valve opened and closed by relying on the pressure of the medium itself, without manual switch. Plastic Check Valve is divided into Swing Check Valve and ball core check valve according to the structure. The connection methods are flange type, wafer type, socket welding type, etc.


The swing check valve uses the rotation of valve plate to open and close, which is suitable for horizontal installation. The ball core check valve uses the up and down movement of the ball core to open and close the valve, which is generally suitable for longitudinal installation.


The plastic check valve is made of UPVC, CPVC, PVDF, PP, PPH materials which are not used according to the use conditions. The service temperature is generally 0 ℃ ~ 140 ℃, and the service pressure is generally less than 1.0MPa.


PVC check valve body is light in weight, compact and beautiful in structure, easy to install, strong in corrosion resistance, wear-resistant, easy to disassemble, easy to maintain and easy to operate, suitable for fluid: water, oil, corrosive chemical liquid.


It is widely used in chemical industry, such as pure water and raw water pipeline system, drainage and sewage pipeline system, brine and sea water pipeline system, acid-base and chemical solution system.
