¾" PPR Check Valve — Non-Return Valve for PPR Pipe Systems
Stop Backflow Before It Starts — Automatic, Reliable, Maintenance-Free
The ¾" PPR Check Valve is a precision-engineered one-way valve designed to prevent backflow in PPR pipe systems automatically. Made from high-grade green PPR (Polypropylene Random Copolymer), it features heat-fusion socket connections on both ends and a clearly embossed flow direction arrow on the body — making installation foolproof. Once installed, it works silently and automatically, protecting your pumps, pipelines, and water supply from reverse flow damage without any manual intervention.
Key Features
- Size: ¾ inch (DN20) — fits standard ¾" PPR pipes
- Material: High-grade green PPR — corrosion-resistant, heat-resistant, and non-toxic
- Connection Type: Heat-fusion (butt welding) socket on both ends for permanent, leak-free bond
- Mechanism: Spring-loaded internal check mechanism — opens with forward flow, closes instantly on backflow
- Flow Indicator: Directional arrow embossed on body for correct installation orientation
- Body Design: Ribbed grip sections on both ends for secure handling during heat fusion
How It Works
Water flowing in the correct direction pushes open the internal check mechanism, allowing free flow. The moment pressure drops or reverses, the spring-loaded mechanism closes automatically — blocking backflow instantly. No manual operation needed, ever.
Common Applications
- Pump discharge lines — prevents water hammer and pump damage
- Borehole and submersible pump installations
- Domestic water supply and distribution systems
- Irrigation and garden water systems
- Solar water heater and hot water circulation systems
- Industrial PPR piping systems
