Description
The Automatic Continuous Acting Air Release valve ("High pressure") discharges accumulated air from the system while it is under pressure. This revolutionary valve is the result of development based on many years of experience.
The Automatic Continuous Acting Air Release valve is the first of its kind in the world. In spite of its compact and light weight structure, it has a 0.0186 sq.in orifice that enables it to discharge air at high flow rates and is not exposed to obstruction by debris.

Main Features
• Working pressure range: 3 - 250 psi. Testing pressure: 360 psi.
• Maximum working temperature 203° f.
• The larger than usual orifice enables it to discharge air at higher flow rates than other Automatic Continuous Acting Air Release valves of its kind.
• The enlarged orifice is not exposed to obstruction by debris.
• The valve's design Rolling Seal Mechanism, is less sensitive to pressure differentials than a direct float seal. It accomplishes a comparably large, orifice for a wide pressure range (up to 250 psi).
• Light weight, simple and reliable structure.
• The body is made of high strength plastic, and all operating parts are made of specially selected corrosion resistant materials.
• A drainage outlet enables removal of excess fluids.

Valve Selection
• Available in male threaded sizes: 1/2", 3/4", 1" - NPT.
• Vacuum check valve - The valve is available as a valve that will only release air from the system and will not admit air to the system when negative pressure conditions occur. This characteristic is obtained by adding a check valve to the air outlet.

Ordering:
