Priority valve with pressure regulator VV300, DN 65 VV300-65A

Priority valve with pressure regulator – reliable installation protection

This valve, combining the functions of a regulator and pressure limiter, is a key element in drinking water distribution systems. Its main task is to ensure priority supply to particularly important parts of the installation, while protecting the remaining sections from insufficient pressure. This solution is ideal for both residential and industrial buildings where continuity of water supply is crucial.

The VV300 valve not only guarantees stable output pressure but also protects the downstream installation from exceeding permissible values. Its compact design makes it perfect for places with limited space, e.g., in installation ducts. This makes installation simple and does not require major modifications.

Functionality and application

The priority valve with pressure regulator finds wide application in systems:

• Supplying residential and public buildings
• Fire protection installations – providing priority supply for hydrants and extinguishing systems
• Industrial processes requiring stable water pressure
• Irrigation systems – maintaining optimal pressure for efficient operation of nozzles and sprinklers

Thanks to the possibility of adjusting the output pressure (in the range of 1 to 12 bar), the valve's operation can be adapted to the specific needs of a given installation. This allows for optimizing water consumption and increasing the efficiency of the entire system. Additionally, the built-in filter protects against damage caused by impurities in the water.

Construction and operating parameters

The VV300 valve is characterized by a solid construction made of spheroidal graphite cast iron GGG40 with a powder coating, which ensures high corrosion resistance and long-term reliability. The body is coated with a toxicologically safe powder material, guaranteeing safety even in contact with drinking water. The maximum working pressure is 16 bar, and the operating temperature is up to 80°C. The minimum inlet pressure is 0.7 bar. The compact design facilitates installation and servicing of the device. The valve complies with BSEN 1567 standard and has DVGW, WRAS (up to 23°C) and PZH certificates, confirming its high quality and compliance with applicable standards.
