Air Release Valve 3/4 IN, Antivacuum

Application

Vacuum breaker air valve, designed to eff­ectively admit air at high flow rates during drainage and in case of pumping interruption or water column separation.

Recommended as safety valve in drip irrigation systems, breaking the system vacuum and preventing dirt suction into the drippers.

For correct operation, the valve should always be in a vertical position. It is recommended to install a manual ball valve under the ARV, in order to make maintenance and repair operations easier without shutting the whole system.

Performance

Prevents pipes from collapsing (Vacuum). At the smallest decrease in pressure, the float drops and opens the seal allowing outside air to enter the pipe immediately.

In drip irrigation systems, this performance helps avoiding dirt suction into the drippers.

Advantages

• The valve has a large hole, with a special seal system, capable of admitting high air ‑ow rates.
• Simple in design, with only 5 parts, it's easy to disassemble for maintenance and cleaning when needed.
•  Its body features a built-in filter to prevent objects, such as insects and leaves, from getting into the valve through the outlet.
• Owing to a perfect t, the valve is totally sealed at low pressures .
