Excellent quality and compact designs for use on water, compressed air and insert gas installations. Simplicity of design eliminates the need for levers and complicated mechanical operations.


The advantages of "Anti-Shock" air release and vacuum break valves are:

Surge Protection
Water line protection from the destructive surge and water hammer phenomena.

Air Release
Effective discharge mechanism to ensure de-aeration under all pipeline flow and operation conditions.

Vacuum Protection
Ensures the least possible resistance to the intake of air and thus preventing vacuum being formed in the pipeline.

This valve design provides the most comprehensive, effective and efficient pipeline protection relative to initial cost of any other available pipeline component. The basis of the design is in the understanding of the physical laws that govern air valve and pipeline operation. Reaction to pipeline dynamics is therefore instantaneous and protection provided is relevant to the pipeline's needs.

This valve is maintenance free and costructed from corrosion and erosion resistant materials for dependable and lasting pipeline protection. Conventional sewage air valves are presented with major funtional problems when operating on sewage and effluent pipelines transporting solids and other viscous substances. This sewage air valve is a unique operating concept that has proven unsurpassed for air/gas release, vaccum protection and surge alleviation.
