RPS Air Release Valves from Vent-O-Mat® are lightweight air release valves developed for irrigation applications. The RPS Series supports controlled pressurized air release and vacuum break functionality, depending on configuration, helping protect irrigation pipelines during filling, operation, and pressure changes.
Its compact design, UV-stabilized construction, and self-cleaning operation make it suited for outdoor water-handling environments where reliable air management is important.
By reducing water hammer and supporting efficient valve action, RPS valves help maintain pipeline performance while offering a lightweight alternative to heavier valve designs.
They are well suited for irrigation systems requiring dependable air release, vacuum protection, and compact installation options.
