FEP ptfe coated Wafer Check Valve and pfa coated Two Way Return Valve manufacturer in India
PTFE Check Valve is a type of check valve that is used to control the fluid flow rate inside the piping system. The check valves allow for the liquid to flow only in one direction. When backflow is attempted the valve closes automatically. The ptfe lined swing check valve is one type of check valve that has a swing to control the flow and the interior of the valve is coated with PTFE synthetic polymer. There are different types of check valves such as the swing, disc and ball check valves. Each differs from the other in the means of controlling the flow. The ptfe lined ball check valves are coated with the polymer inside so that the erosion and corrosion by the liquid inside is minimized. The core material used for the manufacturing of the valves stays intact from the inner environment of the valves.

There are different types of materials used for the production of the valves such as ductile iron, carbon steel, cast iron and other material types. The sizes of the PFA Check Valve vary according to the different standards they are made up of.
Table of Content
The standards govern the valves from ½ inches through 48 inches and above for special purpose applications. The pressure range is from PN10 through PN16. The pfa lined check valve is used in water lines, oil and gas transmission lines, waste water management systems and in petroleum applications to regulate and check the flow only in one direction.

- When Installed Vertically (or upto 60° angle) check valve close automatically because of centre guided ball.
- When Installed Horizontally (90° to 60°), the valve close automatically if the back flow related to water is 1.5 – 2.5 m/sec.
- Full Bore when valve is opened. i.e. Low Pressure Drop condition.
