Automatic Air Release Valve series are specifically designed to meet the requirements of water utility systems, greatly improving supply and distribution system efficiency. We place special focus on ensuring that our products meet all applicable standards and specifications prescribed by the industry. From the most complex of applications to the simplest, our automatic Air Release Valve series perform with precision and accuracy to provide exact control of pressure, flow, level, surge and pump control.

Automatic Recirculation Valves protect centrifugal pumps from damage that may occur during low-flow operations. Minimum flow protection is accomplished with an automatic, modulating bypass that assures smooth pump operation between the minimum and maximum flow point on the pump curve.

No external power source is required. These valves are self-contained and simplify the system design and installation. Sizes range from 1 inch to 24 inches, including ANSI Class 150 through 2500 lb. Valve internals are stainless steel with housing in carbon steel, stainless steel, or special machinable alloys.​
