Introducing the Tempo 478ASV Anti-Siphon Valve, a crucial component in maintaining the proper water flow and pressure in various plumbing systems. This valve is specifically designed to prevent the backflow of water caused by negative pressure, making it an essential addition to irrigation, fire protection, and industrial applications.

The Tempo 478ASV Anti-Siphon Valve is a diaphragm-operated, single check valve. Its body is constructed from high-quality brass, ensuring both durability and corrosion resistance. The valve's diaphragm is made from an elastomer material that provides excellent flexibility and resistance to wear and tear.

The valve operates automatically, opening when water pressure is present and closing when pressure drops. This mechanism helps ensure that water flows in the intended direction and that no contaminated water from a potentially lower source can enter the system. The valve's design also allows for easy installation, with only two bolts required to secure it in place.

The Tempo 478ASV Anti-Siphon Valve features a large 1/2" inlet and outlet, making it suitable for use in systems with moderate to high water flow requirements. The valve's operating pressure range is from 0 to 150 psi (0 to 10.3 bar), making it versatile enough for use in a variety of applications.

In addition to its primary function as an anti-siphon valve, the Tempo 478ASV also serves as a backflow preventer, protecting your plumbing system from potential contamination. Its compact design, combined with its reliable performance and easy installation, makes it an excellent choice for a wide range of applications.

The Tempo 478ASV Anti-Siphon Valve is the ideal solution for maintaining the proper water flow and pressure in your plumbing system, while also protecting it from potential contamination. Whether you're installing an irrigation system, setting up a fire protection system, or working on an industrial application, this valve is an essential component that you can trust to perform reliably.
