Midland Industries 940365B Y-pattern Swing Check Valve

Product Description

The MIDLAND INDUSTRIES 940365B is a Y-pattern swing check valve designed to allow one-directional flow and prevent backflow in fluid piping systems. Built with a cast brass body, this valve delivers corrosion resistance and durability suited to the demands of plumbing and hydronic heating applications. The 1-1/4 inch nominal size with C x C (copper sweat) connections makes it a straightforward fit for copper pipe installations. Licensed plumbers and pipefitters install this type of valve where backflow prevention is required without the use of an external power source or actuation.

This valve is appropriate for residential and light commercial plumbing systems, including domestic water supply lines and hydronic heating loops. The Y-pattern design positions the disc at an angle to the flow path, which reduces turbulence and pressure drop compared to a straight-through check valve. It is typically installed on horizontal or vertical runs where flow direction is consistent and a self-closing check mechanism is required. No compatible model numbers or system families were specified in the product data.

Key Features

• Y-pattern swing disc design reduces flow turbulence and pressure drop
• Cast brass body provides corrosion resistance for water and hydronic applications
• 1-1/4 inch nominal size with C x C connections for copper sweat installations
• Gravity-assisted swing disc closes automatically to stop backflow
• Domestically sourced construction

Compatibility

Designed as an OEM-style replacement or new-installation swing check valve for 1-1/4 inch copper pipe systems in residential and light commercial plumbing and hydronic heating applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting into any existing piping. Sweat solder C x C connections using appropriate flux and lead-free solder per code requirements. Verify the flow direction arrow on the valve body is oriented correctly before making final connections.
