Function and Description

High-Performance Vacuum Relief Valve with Precise Tightness

When the set vacuum Set vacuum Internal negative gauge pressure at which a vacuum valve first opens. is reached, the valve starts to open and reaches full lift Course Lift is the actual travel of the valve pallet from the main valve out of the closed position. within 100% vacuum increase. The tank vacuum is maintained up to the set vacuum with a tightness that is above the normal standards due to our highly developed manufacturing technology. This feature is ensured by valve seats made of high quality stainless steel with precisely lapped valve pallets and a reinforced housing Corps A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. design. After the vacuum is balanced, the valve re-seats and provides a tight seal Joint 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. .

Flow-Optimized Valve Body for Maximum Efficiency

The optimized fluid dynamic design of the valve body and valve pallet Clapet Valve pallet is the generic term for the assembly that rests on the valve seat. is a result of extensive research and development, resulting in stable operation of the valve pallet, optimized performance, and reduced product losses.

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”.
