PTFE Lined Wafer Check Valve
Salient Features
• Meet design specification as per B 16.34 / API 6D.
• Testing Standard as per Mfg. Std.
• Lining Standard as per ASTM F 1545
• The construction of wafer design valves allows them to be sandwiched between flanged section of the pipe lines.
• A High Integrity PFA moulded wafer check valves body, with a fully encapsulated one piece disc / hinge assembly ensuring maintenance free service.
• A valve that is designed to allow the fluid to flow in a given direction but closes to prevent. back flow. Check valves are usually self acting.
• PFA Lined wafer swing check valves are ideal for use in highly corrosive applications.
• These valves can be used in horizontal and vertical installations due to the special design with a face PTFE cover encapsulated body with both side. PTFE Cover supports against the disc to achieve a seal : Open / Close positions within pipeline.
• The disc design can swing freely within piping system interference with the inside diameter of the connecting pipe lines allows to suit both ASME 150# & DIN PN -10 / PN -16 systems.
