Configure compact, inline backflow prevention inside your piping runs with our premium POM plastic insert check valve cores, available at Atradesen.com. Crafted from high-density POM (Polyoxymethylene/Acetal), these cartridge valves are fitted with heavy-duty 304 stainless steel springs and high-grade EPDM gaskets, providing excellent dimensional stability, thermal endurance, and leak-proof seals up to 110°C.
Designed to be pressed directly into matching hoses or rigid piping, this space-saving non-return core instantly stops liquid siphoning and reverse flow, protecting pump impellers and maintaining inline fluid pressure.
Select the optimal internal structure to match your pipeline's fluid dynamics and volume needs:
Review these alignment guidelines prior to installation to ensure a leakage-free fit:
| Feature | Details |
|---|---|
| Body Material | High-Grade POM (Acetal/Polyoxymethylene) - Non-Toxic |
| Spring Material | 304 Stainless Steel (Anti-Rust & Durable) |
| O-Ring Gasket Material | EPDM (Ethylene Propylene Diene Monomer) |
| Max Working Temperature | Up to 110°C (230°F) - Safe for hot water loops |
| Working Pressure Range | 0.05 ~ 1.0 MPa (0.5 ~ 10 Bar) |
| Cracking (Opening) Pressure | 0.005 MPa (0.05 Bar) |
Q: What is the benefit of the guiding fins on the High Flow models?
A: The guide fins hold the inner spring gate in a perfectly concentric position when pushed open by fluid pressure. This prevents turbulent water spin, decreases flow resistance, and allows a higher volume of water to pass through with minimal pressure loss.
Q: Will the EPDM O-ring securely seal against the pipe inner wall without glue?
A: Yes. The rubber O-ring is designed with a slightly larger diameter than the POM casing. When pressed into a matching rigid pipe or hose, the rubber compresses tightly against the inner wall, forming a strong mechanical friction seal that prevents water from bypassing the cartridge.
