Flange type fluorine lined check valve

Short Description:

The flange type fluorine lining check valve is suitable for aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants and FEP of various concentrations from – 50 ℃ to 150 ℃, and also applicable to the pipelines of various concentrations of strong alkali organic solvents and other corrosive gases and liquid media.

The valve is fully lined with Teflon material, which effectively insulates the internal flow medium from the valve body, and has a good anti-corrosion effect, and the valve disc seal is Teflon soft seal, which has a better check effect.
