PVC Butterfly Valve for Water and Compatible Chemical Pipelines This PVC butterfly valve is a wafer-type isolation valve for 2-8 in. pipework. The listed construction uses a U-PVC body and disc, an EPDM seat seal, and a carbon-steel stem. It is suitable for water supply, sewage, HVAC, and compatible chemical process lines. Before ordering, confirm the fluid composition, concentration, operating temperature, pressure, and connection standard with our technical team.

DN200 PVC Butterfly Valve Drawing Dimensions and Selection Use the dimensional drawing below to review the available DN sizes, flange drilling, mounting pattern, and operating torque. For a project quotation, provide the selected size, medium, pressure, temperature, flange standard, quantity, and documentation requirements. How to Select a PVC Butterfly Valve Select the valve by the actual service medium and operating conditions, not by nominal size alone. U-PVC and EPDM are commonly selected for water and compatible services, but chemical compatibility depends on the exact fluid, concentration, temperature, and pressure. If the application requires a different construction, our team can help compare the appropriate butterfly valve range and confirm a suitable option.
