Midland Industries 940359 Brass Swing Check Valve 3 Inch Fpt

Product Description

The MIDLAND INDUSTRIES 940359 is a 3-inch brass swing check valve designed for use in plumbing and piping systems where backflow prevention is required. Built with a C85700 brass body, brass disc, and brass cap, this valve operates on a 90-degree straight pattern and requires just 3 to 5 psi cracking pressure to open. It handles pressures up to 200 psi WOG and operates across a temperature range of -5 to 150 degrees F. The FPT (female pipe thread) connections on both ends allow for straightforward inline installation. This valve is intended for installation by licensed plumbers in commercial and industrial piping systems.

This swing check valve fits residential and commercial water supply, heating, and general fluid-handling systems where a reliable one-way flow device is needed at a 3-inch nominal pipe size. The 90-degree straight pattern body keeps the flow path direct, minimizing pressure drop across the valve. The fiber H seal provides a positive shutoff against reverse flow. Plumbers working on potable water lines should note that this product contains lead and may not be suitable for potable water applications in all jurisdictions. Verify local code requirements before installation.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing codes. Shut off the water supply and depressurize the line fully before threading the valve into the system. Use appropriate pipe thread sealant or PTFE tape on the FPT connections and verify thread engagement is complete before restoring flow.
