PTFE PFA FEP Lined Dual Plate Wafer Check Valve

FVF PTFE PFA FEP Lined Dual Plate Wafer Check Valve

• The dual plate check valve is an all purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or lift check valve. The double plate check valve employs two spring-loaded plates hinged on a central hinge pin.
• In addition to the valve body and valve disc, the return spring is also fully lined with corrosion-resistant fluorine materials. The reasonably designed spring enables the valve disc to generate sufficient sealing specific pressure in the low-pressure area.And it ensures the reliability of the valve sealing in the low pressure area.
• FVF lined check valve is mainly used in chemical industries,such as sulfuric acid, alkali etc.
