Superior 900MA-25S Inline Check Valve 2 5/8 in Ods

Product Description

The SUPERIOR 900MA-25S is an inline check valve designed for use in refrigeration and HVAC systems. It allows refrigerant flow in one direction while preventing backflow, protecting compressors, metering devices, and other system components from reverse pressure. The 900MA-25S features a 2 5/8 inch ODS (Outside Diameter Sweat) connection, making it compatible with copper tubing installations common in commercial and industrial refrigeration pipework. Installation is typically performed by licensed refrigeration technicians or HVAC mechanics working on larger-tonnage systems.

This inline check valve is suited for commercial refrigeration applications where larger-diameter line sets are used. It fits into liquid, suction, or discharge line configurations depending on system design. The 2 5/8 inch ODS sweat connection is a size commonly found in medium to large commercial refrigeration systems, walk-in cooler and freezer installations, and industrial process cooling circuits.

Key Features

• 2 5/8 inch ODS sweat connection for direct copper tubing installation
• Inline check valve design prevents refrigerant backflow and reverse pressure events
• Protects compressors and downstream components from reverse flow damage
• Designed for commercial and industrial refrigeration line set applications

Compatibility

Designed as an OEM-style replacement or new-installation inline check valve for commercial refrigeration systems using 2 5/8 inch ODS copper sweat connections.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Recover and reclaim all system refrigerant in accordance with EPA Section 608 requirements before cutting into the refrigerant circuit. Braze the sweat connections using appropriate brazing alloy with nitrogen purge to prevent internal oxidation. Confirm flow direction markings on the valve body before completing the installation.
