2-inch PVC Inline Swing Check Valve

This 2-inch slip PVC check valve uses an inline swing mechanism to allow full flow in one direction while preventing backflow. It is built for pump applications where a reliable, non-return valve is required in horizontal or vertical piping runs.

4.30 psi maximum pressure at 130 °F

The valve handles water pressure up to 4.30 psi at a maximum temperature of 130 degrees Fahrenheit. It is not rated for steam service and uses a neoprene seal with a PVC seat to maintain closure under these stated limits.

Replaces worn or missing pump check valves

Install this valve when an existing swing check has failed or when a pump discharge line lacks backflow protection. The jump is worth it when the system operates within the 4.30 psi and 130 °F ratings and requires a full-flow 2-inch PVC connection.

Questions about this item

Should I choose the 2" slip PVC model for a standard residential sump pump discharge line?

Yes, the 2 inch slip PVC body matches common residential pump discharge piping and the full-flow design keeps head loss low.

What does the 4.30 psi rating mean when the valve is installed on a typical basement sump system?

It indicates the maximum water pressure the valve can hold at 130 °F; a standard sump pump develops far less pressure, so the valve will not be the limiting factor.

The spec lists clamp x clamp connections — does that restrict the valve to horizontal runs only?

No, the manufacturer rates it for both horizontal and vertical mounting orientations.
