Valve A-80 MAC 1/2 "x3 / 8" without metal nut NOV76MAC Arco

Angle valve 1/2 "Mx3 / 8" M with NOVA metal anti-scale system control and without nut with chrome finish, A-80 MAC series. The A-80 MAC angle valves are used in interior plumbing installations, and their characteristics make them especially suitable to minimize the effects of lime on the valve. They allow to individually cut the water supply or sinks, toilets, cisterns and other points of consumption to proceed with their repair or replacement. These valves are operated by a quarter turn of the knob. Nominal pressure: 16 bar. Temperature range: hot and cold water up to 95ºC. Test pressure: 25 bar. Fluid: drinking water and domestic hot water. The shaft and the ball are made of a single piece. The shaft and the ball are made of a single piece made of a limescale polymer. This arrangement increases its resistance, facilitates a smooth maneuver and prevents lime from adhering to it. This anti-scale ball-shaft has the same design as the brass shaft, used in the A-80 series since its inception, and has the same fundamental characteristics of tightness and low pressure drop, with the additional advantage of preventing the negative effects of lime on the valve. In those installations where the hardness of the water or the temperature facilitate the deposition of lime, generally associated with a low frequency of operation of the valves, there is an increase in the hardness of the operation after long periods of time. The anti-limescale ball-shaft is the solution to prevent this problem, which can render the valve unusable, and keep the flow constant over time by preventing lime from adhering to it, reducing the passage of water.
