PTFE-LINED CHECK VALVES

ptfe lined check valves

This series of process check valves was developed for use on fluids compatible with the corrosion resistant characteristics of virgin TFE. The body of the valve is made from a combination of ductile iron and steel. The body parts do not come into contact with the process flow. End connections are made with a TFE reducing flange. This new series offers high physical strength in combination with the high corrosion resistance of virgin TFE.

This new series offers high physical strength in combination with the high corrosion resistance of virgin TFE. The simple internal design provides for high flow rates at a very low pressure drop. All wetted parts of Chem Flowtronics model 1850 spring loaded check valves are TFE. The housing is a combination of ductile iron and steel.
