Description Angle valve 1/2 male - 3/8 male with anti-lime metal NOVA handle and without nut, chrome finish, A-80 MAC LONG series. The A-80 MAC angle valves are used in interior plumbing installations, and their characteristics make them particularly suitable for minimizing the effects of scale on the valve. They allow the water supply or sinks, lavatories, cisterns and other consumption points to be individually cut off in order to proceed with their repair or replacement.
The shaft and the ball are made of a single piece made of an anti-limescale polymer. This arrangement increases its resistance, facilitates a smooth maneuver and prevents lime from adhering to it.
This anti-limescale ball-pin has the same design as the brass pin, used in the A-80 series since its inception, and has the same fundamental characteristics of sealing 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 maneuvering of the valves, there is an increase in the hardness of the maneuver 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 rate constant over time by preventing limescale from adhering to it, reducing the passage of water.
Characteristics of the long valve A-80 MAC 1/2" male - 3/8" male without nut:
- 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.
