Arita Thermoplastic Check Valve

Engineered to protect sensitive pumps and process equipment from destructive backflow and fluid hammer, our Thermoplastic Check Valve combines advanced engineered polymers (PVC, CPVC, PPH) with a fully non-metallic wetted flow path. Available in True Union Ball, Swing, and Single union configurations, its hydrodynamically smooth internal profile minimizes pressure drop (NPSHr) while providing silent, reliable self-closing action under thermal, hydraulic, and aggressive chemical stress.
