UPVC valves and piping — also called PVC or rigid PVC — are the economical workhorse for corrosion-free flow control in water and dilute-chemical service at ambient temperatures up to 55°C. UPVC (unplasticised polyvinyl chloride) never rusts or scales, weighs a fraction of metal, and keeps system cost low across water treatment, seawater desalination and general plant lines. Huiya supplies a complete UPVC range — pipe, fittings and valves (ball and butterfly), pneumatic or manual — in both DIN metric and ANSI/ASTM Schedule 80 dimensions to suit project specifications worldwide. Every product is backed by a 12-month quality warranty. When your media runs hot or aggressive, step up to CPVC, PPH or PVDF.

UPVC handles many acids and salts at ambient temperature at the lowest cost. Confirm your specific medium and temperature in our chemical compatibility checker.
UPVC is a mainstay of water treatment, from RO feed lines to hypochlorite dosing. See where it fits in our valves for wastewater, desalination, and dosing guide.
UPVC diaphragm valves — also known as PVC diaphragm valves — are the economical workhorse for ambient-temperature water and mild chemical service: industrial and RO water, weak acids and alkalis, salt solutions, and seawater. We supply them in true union, flanged, and pneumatic configurations, built from virgin UPVC (unplasticized PVC) and easy to install with […]

UPVC / PVC Ball Valve UPVC ball valves — also known as PVC ball valves — are the economical workhorse for quarter-turn on/off control of ambient-temperature water and mild chemicals: industrial and RO water, weak acids and alkalis, salt solutions, and seawater. We build ours from virgin UPVC (unplasticized PVC) with a PTFE seat, in

UPVC / PVC Butterfly Valve UPVC butterfly valves — also known as PVC butterfly valves — give you compact, quarter-turn control of large-bore water and mild-chemical lines, DN50 to DN500, in wafer and lug bodies with a UPVC disc and an EPDM or FKM seat. They are the space-saving, economical choice for big-flow isolation and

PVC Pneumatic Butterfly Valve The Huiya PVC pneumatic butterfly valve — UPVC in DIN markets — is a large-bore, wafer-type automated valve for ambient-temperature water, seawater, and wastewater, sizes DN40 to DN500. For pipes above DN100, it’s far lighter and more economical than a flanged ball valve, and its universal slotted-hole flange fits ANSI, DIN,

PVC Flanged Pneumatic Ball Valve The Huiya PVC flanged pneumatic ball valve — UPVC in DIN-standard markets — is a large-bore, full-port automated valve for ambient-temperature water and chemical service, sizes DN15–DN200. Available in ANSI Class 150, DIN PN10, and JIS 10K flange standards, its one-piece molded flange eliminates root leakage — making it ideal
