RBXc Air Release Valves from Vent-O-Mat are designed for water, sewage, and effluent pipeline applications where air discharge, vacuum protection, and surge control are important to system operation.
The RBXc series supports high-capacity air release during pipeline filling, high-volume air intake during draining or column separation, and controlled air discharge once the pipeline is fully charged.

Built with fusion bonded epoxy powder coated ductile iron, these valves are suited for demanding pipeline environments requiring durable construction and dependable performance.
The series also incorporates anti-shock and anti-surge functionality to help reduce the risk of damaging pressure events during pump trip conditions or rapid pipeline filling.
RBXc Air Release Valves are well suited for municipal, industrial, mining, power, chemical, and desalination applications where pipeline protection and air management are critical.
