ARV-1"-A Air Release Valve

DESCRIPTION

This valve is designed to efficiently extract the air trapped in pipes, filters, tanks and other places where unwanted air might cause problems.

The valve has one seal, which expels both kinetic and residual air automatically, and this function is not affected by water pressure.

Its exclusive Y-shaped discharge outlet design allows a much greater air flow than in other valves of this type, in both the intake and the discharge processes.

Owing to a perfect fit, the valve is totally sealed even at very low pressures. Simple in design, with a total of only 5 parts, it's easy to unassemble for maintenance and cleaning when needed. The body is red in color, making it easily visible. The base is 1"M BSP or NPT.

PERFORMANCE

The valve performs three functions:

It extracts the air from pipes as they fill, and when water reaches the inside of the valve, the float rises and seals the discharge outlet.

It exerts continuous automatic control, eliminating any residual air pockets reaching the valve, as the float immediately drops, partly or totally opening the discharge outlet. The internal water pressure does not prevent this function from being carried out.

It prevents pipe collapse, because, at the least decrease in pressure, the float drops, opening the seal and allowing outside air to enter the pipe.
