Product Description

Description

This valve is manufactured entirely from Polypropylene Random (PPR).
It features a one-piece (monolithic) construction that connects to PPR pipes via socket fusion welding, forming a permanent, leak‑free joint.
Operation is manual (90° quarter-turn).
Available nominal sizes range from DN20 to DN63.
Customization options include color, logo, and non‑standard dimensions.

Characteristics & Advantages

Feature	Benefit
All‑PPR construction	Zero metal ion release; ideal for deionised water, beverages, and sensitive processes.
Excellent chemical resistance	Immune to rust, scale, and most dilute acids/alkalis (except strong oxidisers).
One‑piece fusion welding	No threaded or flanged joints – eliminates potential leak paths.
Lightweight & insulation	Approx. 1/5 the weight of a stainless steel valve; electrically non‑conductive, no galvanic corrosion.
Low cost	Economical for mass production and large‑scale residential/light industrial projects.

Applications

Residential plumbing – main shut‑off valves, branch controls for cold/hot water.
Drinking water & purified water systems – pre‑filter isolation, reverse osmosis (RO) lines.
Low‑pressure chemical transfer – mild acidic/alkaline solutions (e.g. electroplating rinse water).
Agricultural irrigation & landscaping – low‑cost, weather‑resistant branch valves.
Temporary or mobile water lines – lightweight and quick fusion welding on site.

Comparison with Stainless Steel Ball Valves (304/316)

Parameter	PPR Plastic Ball Valve	Stainless Steel Ball Valve (304/316)
Material (body & ball)	PPR	304 / 316 stainless steel
Corrosion resistance	Excellent vs. acids, alkalis, salts; no rust	Moderate; susceptible to pitting in chlorides (especially 304)
Metal ion release	None	Traces of Cr, Ni, Fe, Mn
Temperature range	–20 °C to 70 °C (long‑term); peak 95 °C	–40 °C to 200 °C (depending on seat material)
Pressure rating	≤ PN16 (1.6 MPa)	PN16 up to PN100 or higher
Connection method	Socket fusion (permanent, zero leakage)	Threaded, flanged, or welded (requires sealant/gaskets)
Weight (relative)	Very light (~1/5 of SS)	Heavy
Cost	Low	Medium to high (especially 316)
Maintainability	One‑piece – cannot be repaired; cut and re‑weld if damaged	Threaded/flanged types can be disassembled and replaced
Typical application	Domestic water, irrigation, mild chemicals	Oil, steam, high‑pressure gas, food processing (polished finish)
