Priority valve with pressure regulator VV300, DN 80 VV300-80A

Priority valve with pressure regulator – reliable installation protection

The VV300 priority valve is an advanced solution combining the functions of a regulator and a pressure limiter. Its main task is to ensure priority water supply to key parts of the installation, while protecting the remaining sections from insufficient pressure. This is an ideal solution for both installers and end-users who value system stability and safety.

This valve is used wherever protection against excessive pressure and continuous water supply to the most important points are required. Its compact design makes it perfect for places with limited space, e.g. in installation ducts. This makes installation simple and does not require complicated adaptations.

Construction and functionality

The VV300 has been designed with durability and reliability in mind. The body made of spheroidal graphite cast iron GGG40 ensures resistance to corrosion and mechanical damage. The powder coating not only protects against external factors but is also physiologically and toxicologically safe – which is particularly important for drinking water. The built-in mesh filter prevents impurities from entering the valve, and ball valves facilitate servicing and maintenance.

Thanks to the precise adjustment of the output pressure (in the range of 1 to 12 bar) and high accuracy of operation, the VV300 valve guarantees stable operating parameters even with large fluctuations in input pressure. The valve's operation does not require an external power supply, which further increases its reliability and reduces operating costs. Compliance with BSEN 1567 confirms its high quality and safety of use.

Key features and benefits:

• Priority power supply: Ensures a continuous supply of drinking water to the most important points of the installation.
• Overpressure protection: Protects the low-pressure part of the installation from damage caused by excessive pressure.
• Compact design: Allows installation in places with limited space.
• Durability and reliability: Made of high-quality materials resistant to corrosion and mechanical damage (spheroidal graphite cast iron GGG40).
• Precise regulation: Maintains a constant output pressure even with fluctuations at the inlet (adjustment range 1-12 bar).
• Maintenance-free: Operation does not require an external power supply or frequent inspections.
• Built-in filter: Protects against impurities and extends the life of the valve.
• Compliance with standards: Meets the requirements of BSEN 1567, guaranteeing safety of use.
• Wide operating temperature range: Can be used at temperatures up to 80°C

The VV300 valve is an investment in the long-term and trouble-free operation of the water system – both in residential and industrial buildings.
