The müller quadax has introduced quadruple (four offset) butterfly valve QUADAX® for extreme pressure and temperature applications.
Natural gas is a fossil fuel and is usually discovered when searching for oil, which forms underground under comparable conditions. It is condensed to a liquid when it is cooled down to around -162 ° C. The term for this is Liquefied Natural Gas. After being processed in refineries, storage and transport are carried out by seagoing vessels, tank trucks, tank farms and pipelines. There are regions on earth where the construction of LNG pipelines is not possible due to various reasons. In these areas, natural gas can be supplied in larger quantities using LNG technology. Wherever prices for using existing pipelines increase seasonally, LNG can be stored and then transported during off-peak periods.
In response to valves for LNG applications, müller quadax has designed four offset butterfly valve with a round sealing geometry, which suits temperatures of up to minus 196°C, and can perform even at the most extreme pressures.
The four offset design guarantees bubble-free tightness in cryogenic applications and wherever ambient temperatures are a concern. During rapid cooling, for example, when liquid gas is pumped through a pipeline, round sealing geometry ensures a tightness of 100%. In the test, müller quadax achieved leakage values higher than the target in the valve specification guideline BS 6364. With the four offset butterfly valve, costly downtime can be reduced to a minimum and maintenance intervals can be planned more effectively.
