Features

Lightweight UPVC wafer check valve for easy installation and reliable backflow prevention in corrosive or water systems.

✅Corrosion-free UPVC body: The all-plastic construction resists rust, acids, and alkalis, making it ideal for chemical processing and seawater applications.

✅Ultra-slim wafer design: Fits tightly between flanges without requiring extra pipe support, saving installation space and weight.

✅Simple gravity-swing operation: The single disc swings open with flow and closes by gravity/backflow, ensuring reliable one-way control with minimal pressure drop.

✅Easy alignment and installation: Integrated centering eye (hook) helps align the valve correctly between bolts during setup.

✅Complete plastic piping solution: Works perfectly downstream of a (UPVC butterfly valve) for isolation and pairs with (UPVC pipe fittings) to maintain a full non-corrosive system loop.
