Magic Plastics 0801-20H2 – CR2 Corrosion-Resistant Check Valve (2″)
Product Overview
The Magic Plastics 0801-20H2 is the CR2 series corrosion-resistant check valve designed for pool/spa systems. It offers full-flow performance and durability in aggressive chemical and chlorinator environments, protecting downstream equipment while maintaining circulation.
Key Features
- 2″ IPS (2″ slip / 2½″ spigot) dual-sized connection for versatile installation.
- Corrosion-resistant construction: glass-filled Noryl shaft and 100% silicone gasket for long life in harsh water conditions.
- Hastelloy spring mechanism allows the valve to be installed in any orientation.
- Clear sight-glass lid for visual inspection of gate movement and internal flow.
- Full-flow design minimizes pressure drop and cavitation in the closed position.
Technical Specifications
- Part Number: 0801-20H2
- Valve Type: CR2 corrosion-resistant spring-loaded check valve
- Connection Sizes: 2″ slip (primary) with 2½″ spigot option—reducers available for 1½″
- Installation Orientation: Any (horizontal, vertical) thanks to spring-loaded gate
- Application: Pool/spa circulation systems, chlorinator protection, corrosive plumbing environments
Applications & Compatibility
This check valve is ideal when you need to prevent back-flow in a pool or spa plumbing circuit—especially where inline chlorinators or salt systems are present. The corrosion-resistant materials make it suitable for harsh water or chemical conditions. Verify that your pipe size is 2″ or use the proper reducer for smaller lines.
Installation Instructions
- Shut off pump and relieve pressure from the line.
- Confirm flow direction arrow on valve aligns with actual water flow.
- Glue the 2″ slip or spigot end into existing plumbing or use adapter/reducer as needed for smaller sizes.
- Secure in place, restore circulation and inspect for correct gate seating via lid sight-glass.
Troubleshooting
- Valve allows reverse flow: Check for debris or worn gasket, confirm spring gate is intact.
- High pressure drop or cavitation: Make sure full-flow path isn’t restricted, inspect for scale or buildup inside valve.
- Gate wont close fully: Verify valve orientation, ensure correct installation and that spring is functional.
Maintenance Tip
Inspect the valve annually for signs of chemical attack, check sight-glass for gate motion and clean any buildup. Replace if the silicone gasket hardens or the spring loses tension. Using a high-quality check valve like the 0801-20H2 helps extend the life of your downstream pool or spa equipment by preventing harmful back-flow.
