Midland Industries 949488 Wye Spring Check Valve 2in Fpt Ss

Product Description

The MIDLAND INDUSTRIES 949488 is a wye-pattern spring check valve designed to allow unidirectional flow while preventing backflow in fluid systems. The valve body is constructed from CF8M/CF8 stainless steel, with a PTFE seat and seal and a 304 stainless steel disc for corrosion resistance across a wide range of media. Rated to 800 psi and suitable for temperatures from -14 to 300 degrees F, it is built for demanding industrial and commercial piping applications. FPT end connections on the 2-inch nominal size allow for straightforward threaded installation by licensed plumbers and pipefitters.

This check valve is suited for use in industrial process piping, commercial plumbing, and fluid handling systems where backflow prevention is required. The wye-style body geometry reduces pressure drop compared to swing-style designs, making it appropriate for higher-flow or continuous-duty installations. The 1.5 psi opening pressure makes it responsive under normal flow conditions. It is installed in horizontal or inline positions and is a common choice in systems handling water, steam, and compatible chemical media.

Key Features

• CF8M/CF8 stainless steel body and cap for corrosion resistance in demanding service conditions
• PTFE seat and seal provide chemical compatibility with a broad range of fluid media
• 304 stainless steel disc, bolt, and spring for all-stainless internal construction
• 800 psi pressure rating suitable for high-pressure system applications
• 1.5 psi low opening pressure for responsive, low-resistance backflow prevention
• FPT connections for standard threaded pipe installation

Compatibility

Designed as an OEM-style replacement or new-installation component for 2-inch FPT threaded stainless steel piping systems requiring spring-loaded wye check valve service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and ASME B31 piping codes. Depressurize and isolate the line before installation and verify that the flow arrow on the valve body is aligned with system flow direction. Use appropriate thread sealant compatible with the system media and the PTFE internal components. Do not exceed the rated pressure or temperature limits of the valve.
