Danfoss OFC Check and Stop Valve

Product Overview

The Danfoss OFC type check and stop valve is engineered to enhance the performance and reliability of oil-free centrifugal compressors. This valve integrates multiple functions, including a damped check valve, a stop valve, and a diffuser, into a single unit. It is specifically designed for use with Danfoss Turbocor compressors (TTS, TGS, TTH, TGH series) and is compatible with various refrigerants, including R134a, R513A, R1234ze(E), and R515B.

Key features include a fast-closing nozzle check valve, PTFE protection against refrigerant migration, a gas damper to prevent violent movements during surge conditions, and a decoupled stop function for improved sealing reliability. The valve also incorporates a sight glass for visual monitoring of refrigerant flow and a pressure port for high-pressure cut-out connections.

Typical applications for the OFC valve span various oil-free HVAC systems, such as air-cooled chillers, water-cooled chillers, and water-to-water heat pumps.
