Applications

They are specifically designed for LNG applications, where control and maintenance work can be carried out safely and simply in the installed position without further risks for the maintenance personnel.

The heat transfer medium is either HTF (Heat Transfer Fluid) or molten salt. Temperatures of up to +500°C can be reached. This heat is then used either as industrial process heat or used for steam generation.

Whether the valves are used in air decomposers or for the control of liquid gases in tank installations or for the handling of gaseous gases in gas mixers, Quadax® butterfly valves reliably meet the high requirements.

In a downstream condenser, the liquid decompressed steam is then cooled down to a range of approx. +70°C to +140°C depending on the heat demand before the warm water is delivered to industry or households via a district heating network.

Not only in nuclear energy, also in the processing of fossil fuels e.g. in gas turbines or power plants with combined heat and power generation and in the conversion of regenerative energy sources

Hydrogen is applied in chemical processes for the production of synthetic fuels derived from gas, coal or biomass. In addition, hydrogen fuel cells as environmentally friendly energy converters are important in the field of electromobility. 

Quadax® butterfly valves are used in secondary and tertiary conveying for the injection of natural gas, hot steam or other fluids under high pressure to increase the production rate of the crude oil reservoir or to increase the viscosity of the crude oil.

The customer was experiencing constant flange leakage on their nitric acid lines due to the use of traditional spiral-wound gaskets, leading to regular expensive shutdowns and HSE implications.
