Protect your valuable pumps, heaters, and filters from potentially damaging backflow issues with the Praher Plastics CV2-2010 Spring Check Valve. This essential plumbing component allows water to flow in one direction only, automatically closing when the flow stops or reverses. Constructed from durable, high-grade CPVC, this valve offers superior resistance to chlorine, acids, ozone, and UV exposure compared to standard PVC alternatives.
Designed with versatility in mind, the valve features 2-inch inner diameter (socket) by 2.5-inch outer diameter (spigot) connections, making it compatible with various Schedule 40 or 80 PVC/CPVC piping configurations. The robust internal spring mechanism ensures a reliable, low-pressure seal while maintaining a high flow rate (up to 75 GPM). It is ideal for use in swimming pool plumbing (especially for booster pumps or elevated returns), irrigation systems, and light industrial applications.
Key Features
- Backflow Prevention: Automatically stops the reversal of water flow to protect pumps and sensitive equipment.
- Durable CPVC Construction: Made from chlorine, acid, and ozone-resistant CPVC material for superior longevity in harsh environments.
- Versatile Connections: Features 2-inch inner diameter (socket) and 2.5-inch outer diameter (spigot) connections for flexible plumbing integration.
- High-Heat Tolerance: Engineered with CPVC body components that resist warping, making it ideal for outdoor and high-temperature environments.
- Reliable Performance: Uses a robust stainless steel spring mechanism and a high-grade O-ring seal to ensure effective, long-term non-return functionality.
- High Flow, Low PSI Loss: Designed for optimal hydraulic efficiency with minimal pressure drop (rated up to 75 GPM).

?? Warnings and Disclaimers
- Pressure Rating: The maximum pressure rating of PVC piping decreases as temperature increases. Follow manufacturer de-rating charts.
- Installation: Always use a proper PVC primer and cement for installation. Ensure the valve is oriented correctly; an arrow on the body indicates the direction of flow.
- Application: NOT FOR USE WITH COMPRESSED AIR OR GASES. This valve is designed for non-potable and potable water liquid systems only.
- Flow Velocity: Flow velocity through the valve should not exceed 5 feet per second for optimal, quiet operation.
?? Professional Tips
- Dual-Size Advantage: This valve is versatile, designed with an outer socket that fits 2.5" pipe and an inner socket that fits 2" pipe, providing flexibility during plumbing configuration.
- Reduces Noise: The spring-loaded poppet design helps prevent the loud "water hammer" or "clunking" sound often associated with flapper-style check valves when the flow stops suddenly.
- Serviceability: The true-union design allows the center body of the valve to be removed from the pipeline for seal maintenance or replacement without needing to cut the pipe.
