Priority valve with pressure regulator VV300, DN 50 VV300-50A

Priority valve with pressure regulator – reliable installation protection

This valve, combining the functions of a regulator and a pressure limiter, is a key element of every water supply installation where maintaining constant pressure for critical consumers is a priority. VV300 with DN 50 effectively protects the remaining parts of the installation, supplying them only after the appropriate drinking water pressure is reached. This is an ideal solution for installers who value reliability and ease of installation, as well as for end-users who expect a stable and safe access to water.

Design and operating principle

The VV300 valve is characterized by a compact design, which facilitates its installation even in limited spaces – for example, in installation ducts. Its operation is based on precise regulation of the inlet pressure and automatic switching of the flow to the remaining parts of the installation when the set pressure is reached. The built-in filter protects against contaminants, and the pilot valves ensure high accuracy of regulation even under variable operating conditions. This ensures the system operates reliably and efficiently for a long time.

The valve remains closed until the required inlet pressure is reached, guaranteeing protection against damage caused by excessive pressure. Maintaining a constant set pressure, even with fluctuations in the water supply network, is another important advantage of this solution.

Features and benefits in practice

• Priority power supply: Ensures constant access to water at the required pressure for the most important draw-off points.
• Overpressure protection: Protects the downstream installation from exceeding the permissible working pressure (maximum 16 bar).
• High regulation accuracy: Maintains stable pressure even under variable operating conditions and low flow rates.
• Built-in filter: Protects the valve and installation from mechanical impurities.
• Compact design: Facilitates installation in tight spaces.
• Wide adjustment range: Allows you to adjust the output pressure to individual needs (from 1 to 12 bar).
• Durability and reliability: Made of high-quality materials (brass, spheroidal cast iron, stainless steel) ensures long-term operation.
• Certificates: Has DVGW, WRAS (up to 23°C) and PZH certificates, confirming compliance with applicable safety and quality standards.
• Easy servicing: Availability of spare parts facilitates maintenance and repairs.

The VV300 valve is an investment in the safety and comfort of using the water supply installation – both in residential and commercial buildings.
