RF Valves RGXII Air Release Valve

RGXII Air Release Valves from RF Valves are Vent-O-Mat air release and vacuum break valves designed for sewage, slurry, effluent, and other demanding pipeline applications.

The RGXII series supports high-capacity air discharge during pipeline filling, high-volume air intake during draining or column separation, and controlled pressurized air release once the pipeline is fully charged.

Process Controls Corporation - RGXII Air Release Valve

Built with anti-shock and anti-surge functionality, RGXII valves help protect pipelines from surge events caused by pump trip, rapid filling, and changing flow conditions. Their compact profile makes them well suited for new installations, retrofit projects, and locations where space or existing piping layouts must be considered.

With low-head sealing capability and available standard, biased, and flanged/threaded outlet configurations, RGXII Air Release Valves provide a strong option for pipeline systems requiring dependable air management in lower-pressure or challenging service environments.
