Ruisongbuild Industrial Swing Check Valves: The Ultimate Backflow Solution

In corrosive fluid management, a reliable non-return valve is critical for system safety. Ruisongbuild’s Plastic Swing Check Valves are designed to automatically prevent the reversal of flow in a piping system. Available in five distinct high-performance polymers, our valves offer a lightweight, cost-effective, and 100% corrosion-free alternative to expensive metallic check valves, ensuring long-term protection for your pumps and instrumentation.

Material Selection Guide: Choosing the Right Polymer

• 聚氯乙烯 (Standard): Best for general water treatment and mild chemicals (up to 60°C).

• 聚氯乙烯 (Hot Water): Superior for hot corrosive fluids and industrial hot water (up to 95°C).

• PPH (Acid/Alkali): Excellent impact strength and chemical resistance for industrial processing (up to 90°C).

• PVDF (Extreme Chemical): The gold standard for ultra-pure water and highly aggressive acids/halogens (up to 140°C).

• FRPP (Reinforced): Glass-fiber reinforced for enhanced structural rigidity and chemical stability.

Technical Specifications

• Size Range: DN20 (3/4″) to DN300 (12″) .

• Connection Type: Flanged (ANSI/DIN/JIS/ISO) or Socket/Threaded.

• Sealing Material: EPDM, FPM (Viton) for maximum chemical compatibility.

• Pressure Rating: PN10, PN16, or Class 150.

• Operation: Gravity-assisted swing flap (Minimal cracking pressure required).
