AIR VENTS

Air Vents are critical components to any irrigation system.  The ability to release entrapped air and provide vacuum relief can prevent major damage to pipelines. Fresno Valves & Castings, Inc. is very proud of the performance of both of these quality Air Vents.

Series 3000 Air Vent and Vacuum Relief Valve is designed for use in pressure or gravity water control systems to allow air to escape during pipeline filling and to prevent vacuum locks while the pipeline empties.
Series 3500 Continuous Acting Air Vent exhausts large volumes of air and is designed for use near pumps or intakes, on pressure boxes and near check valves.
