Emerson Flow Control (Alco) 064993 ODF Check Valve - 1-5/8

The Emerson Flow Control (Alco) 064993 is a refrigeration check valve designed with 1-5/8" ODF (Outside Diameter Flare) connections for use in commercial and industrial refrigeration systems. This check valve ensures one-way flow of refrigerant, preventing reverse flow and backflow that could compromise system efficiency and component protection.

Key Features:

• 1-5/8" ODF brass connections for reliable brazing installation
• Low pressure drop design maintains system efficiency
• Spring-loaded disc mechanism ensures positive sealing
• Suitable for use with HFC, HCFC, and CFC refrigerants
• Durable brass body construction for long service life
• Bidirectional mounting capability for installation flexibility

This check valve is commonly installed in discharge lines, hot gas bypass lines, and other refrigeration circuit locations where backflow prevention is critical. The ODF connection style allows for permanent brazing into copper refrigeration piping systems. Manufactured by Alco Controls, now part of Emerson Flow Control, this valve meets industry standards for commercial refrigeration applications.
