AV-4UPV UPVC Diaphragm Valve

UPVC Diaphragm Valve Description

The UPVC diaphragm valve is suitable for the transmission of corrosion medium and the regulation of the flow and interception. The overflow components are assembled by RPP or PVDF injection parts. It has excellent corrosion resistance and lightweight, is a good replacement of stainless steel valves in some cases. The sealing diaphragm of the UPVC diaphragm valve uses F46 or PFA, which can fold more than 1200 times. The screw lifting structure made the opening and closing moment is large and stable.
