The Phillips® 270A High Side Float Valve, opening on a rise in level, will transfer oil from a discharge line oil separator to the crankcase of the compressor, or to an oil reservoir. This valve is used for oil in ammonia (R-717) and halocarbon systems.

The all-steel valve has a simple needle and seat, and is available with or without chamber. Ductile iron or cast chambers are available for external mounting.  Flanges are available for internal mounting.
