Vacuum Relief Valve

in a special heat jacketed design

Функция и описание

The SV/T-0-H type PROTEGO® valve is a highly developed vacuum relief valve with a valve housing that comes with a heating jacket down to the flange. It is primarily used as a safety device for inbreathing to tanks, containers, and process engineering equipment under difficult operating conditions. This includes extreme weather conditions or products that tend to form polymers at certain temperatures, adhere, or form deposits that negatively influence function (such as bitumen, tar, dust). The valve offers reliable protection against vacuum and prevents the intake of air close to the set vacuum.

When the set vacuum is reached, the valve starts to open and reaches full lift within a 40% vacuum increase. Up to the set vacuum, the tank vacuum is maintained with a seal that is far superior to the conventional standard due to the highly developed manufacturing technology. This feature is achieved by valve seats made of high quality stainless steel with precisely lapped valve pallets and a reinforced housing design. After the vacuum is relieved, the valve reseats and again provides a tight seal.

Диаграммы пропускной способности

Диаграммы пропускной способности были определены с помощью калибрированной и сертифицированной объединением технического надзора (TÜV) проточной измерительной установки. Пропускная способность V. в м³/час определена воздухом при нормальных атмосферных условиях в соответствии с ISO 6358 (20°C, 1 бар). Преобразование для различных плотностей и температур см. главу 1: Технические основы
