Air Release Valve 2-K COMPACT

Application

Designed to efficiently extract air trapped in medium-sized pipes, large fil­ters, tanks and other places where the absence of air is required for correct functioning.

The release valves are located at the outlet of pipes whose slope varies according to the hydraulic gradient, in areas where pipes are located above ground level, in long pipes with uniform slope, at the input of measuring instruments, the output of reducing valves, in diameter reductions, pumps, ­filtration systems, on both sides of a subterranean crossing road.

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

• Extracts the air trapped in pipes as they _ll. When water reaches the inside of the valve, the _oat rises, shutting the outlet (KINETIC).
• Prevents pipes from collapsing. At the smallest decrease in pressure, the _oat drops and opens the seal allowing outside air to enter the pipe immediately (AIR VACUUM RELIEF).

Advantages

• New compact design more sustainable and competitive with similar quality and performance as the rest of our air valves.
• Owing to a perfect inner _nish, the valve is totally sealed even at very low pressures.
• With just five parts, it's very easy to disassemble when it needs to be cleaned.
• Its outlet features a threaded elbow to provide a wider range of connection possibilities, as it's easily detachable, offering a vertical outlet.
• Owing to its exclusive internal design, the air stream will not drag the float up, even when air is faster than the speed of sound at the outlet. Only water will cause the float to rise.
• Includes an internal grille in the elbow to prevent foreign bodies from entering the valve.
