Función y descripción

Highly Developed Vacuum Relief Valve

The SV/T-0-H Type PROTEGO® valve is a highly developed vacuum relief valve Vacuum relief valve A vacuum relief valve is used to ventilate a part of the system and protects it from impermissible underpressure. with a valve housing Housing A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. that is equipped with a heating jacket that can be heated up to the flange. It is primarily used as a device Device 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. for in-breathing in tanks, containers, and process engineering equipment Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. under difficult operating conditions. This includes extreme weather conditions or products that tend to form polymers at certain temperatures, stick together, or form deposits that negatively influence function (such as bitumen, tar, dust). The valve offers reliable protection against vacuum Vacuum Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. and prevents air intake almost up to the set vacuum Set vacuum Internal negative gauge pressure at which a vacuum valve first opens. .

Advanced Manufacturing Technology

When the set vacuum is reached, the valve starts to open and reaches full lift Lift Lift is the actual travel of the valve pallet from the main valve out of the closed position. within a 40% vacuum increase. Up to the set vacuum, the tank vacuum is maintained with a seal Seal A seal prevents or limits unwanted transfer of product from one container to another. Seal is used as superordinate term for all types of sealing elements. 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 sturdy housing design. After the vacuum is released, the valve re-seats and again provides a tight seal.

Diagrama de flujo volumétrico

Los diagramas de flujo volumétrico han sido determinados con un banco de pruebas de caudal calibrado y certifi - cado por TÜV. El flujo volumétrico V. en [m³/h] y el CFH se refi eren a las condiciones estándar de referencia de aire según ISO 6358 (20°C, 1bar). La conversión a otras densidades y temperaturas están referidas en el Vol. 1: “Fundamentos Técnicos”.
