UPVC Valves
Plastic Wafer Butterfly & Ball Valves | DN50 - DN300 | Corrosion Proof
ZNX UPVC, CPVC and PVDF plastic valves deliver metal-free corrosion resistance for swimming pools, aquaculture, irrigation networks, chemical dosing skid lines, seawater service and laboratory water systems. The injection-moulded UPVC body weighs a fraction of a metal valve and never rusts or scales.
Available as wafer butterfly valves (DN50-DN300) and true-union ball valves (DN15-DN100) with EPDM or FKM (Viton) seals. Compatible with DIN, ANSI, JIS and metric pipe standards.

Key Features
- Plastic body — never rusts, scales or corrodes
- Lightweight — less than 1/4 the weight of metal valves
- Smooth internal bore — low pressure drop, no fouling
- Compatible with chemical dosing (chlorine, acids, alkalis)
- True-union ball valves allow easy inline servicing
- Cost-effective alternative to stainless steel in many services
- EPDM or FKM seals cover most water and chemical media
Applications
- Swimming pool filtration and circulation
- Aquaculture (fish farm, shrimp pond) water systems
- Landscape irrigation and agricultural water distribution
- Chemical dosing and injection skid packages
- Seawater intake for marine and offshore
- RO system permeate and concentrate lines
- Laboratory ultrapure water and waste systems
