Function and Description
Highly Developed Vacuum Relief Valve
The PROTEGO® V/SV-XXL valve is a highly developed optimized
vacuum relief valve
Soupape de dépression
A vacuum relief valve is used to ventilate a part of the system and protects it from impermissible underpressure.
with excellent flow performance. It is primarily used as a

Appareil
A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow.

Dépression
Vacuum is the pressure in an enclosed space that is lower than the ambient pressure.

This feature is ensured by valve seats made of high quality stainless steel with precisely lapped valve pallets and a reinforced

Diagrama de vazão
Este diagrama de vazão foi determinado em uma bancada de medição de vazão calibrada e certificada pela TÜV. A vazão V em m³/h se refere ao estado técnico padrão de ar, conforme ISO 6358 (20°C, 1bar). Para conversão em outras densidades e temperaturas, veja o cap. 1: Bases técnicas.
