Air Release Valve 3/8"

Air Release Valves (ARV) are an essential component in pipeline systems.air release valve 3/8'' 12.5kg factory They are designed to automatically release any entrained air that collects at the high spots during water transfer, maximizing system efficiency. In addition, they prevent the formation of water hammer under column separation conditions. Air valves can also be fitted with RFP (rapid filling prevention) designs to reduce the potential for rapid pipe fill rates that would generate water hammer in the system.

These small, durable valves are typically installed at the peaks of a system, or paired with a combination air/vacuum valve.air release valve 3/8'' 12.5kg factory They have a small orifice to vent air, and they are often sized according to the amount of head loss or pressure drop the system experiences on the discharge side.

When an air valve becomes full of air, an internal lever mechanism multiplies the force on the float to create a greater than internal pressure and opens the orifice. Liquid then flows in through the float and down into the body, pushing the float up until the seat presses against the orifice, closing the valve and venting the air. The valve will then re-open when the orifice is empty to allow the system to drain at a controlled rate, and closes when the orifice is full again, stopping the flow.

These valves are commonly installed on wastewater and potable water systems. They are a great choice for industrial applications, pumping stations and irrigation schemes. They also work well on any closed-loop, pressurized piping that can entrap air. Proper installation is key to ensure the proper functioning of the air release valves. They should be placed at the high points of a system, with the inlet facing down. This helps to prevent external contaminates from fouling the floats and to keep vermin and spiders from entering the body.
