PVC Check Valve 50mm Swing

Product Description 

The 50mm PVC Swing Check Valve is a reliable non‑return valve designed to prevent backflow in spa and pool plumbing systems. Commonly used with Cyclone filtration systems, this valve helps maintain correct water circulation and protects pumps, heaters, and filtration equipment from reverse water flow.

Manufactured from durable, chemical‑resistant PVC, the swing‑flap design allows smooth, unrestricted forward flow while automatically closing when water pressure drops. This makes it ideal for high‑flow spa and swim spa installations where performance and longevity are essential.

Suitable for both new installations and replacement applications, this check valve is compatible with standard 50mm solvent‑weld plumbing.
