Hornung GmbH is a manufacturer of high-purity gas systems and high-purity gas valves, among others. for laboratory and analytics, up to a gas purity 6.0.

During the production of our products and gas systems, the highest demands are placed on the materials, their surface properties, as well as on the series-specific cleaning and testing steps. Our strength is the manufacture of complex pressure regulating valves including leak testing with test certificate.

Outstanding quality “Made in Germany”, fast availability and individual solutions distinguish our range of products!

Hornung high purity gas systems and fittings

Our range of high purity gas systems and fittings includes:

We supply our fittings for high purity gases up to a prepressure (input pressure) of max. 440 bar. In the output pressure, our performance spectrum covers the following range, starting at 50 mbar up to max. 400 bar. In the output pressure, our performance spectrum covers the following range, starting at 50 mbar up to max. 400 bar.

Our product range includes pressure regulators, gas supply valves and valves made of brass, aluminum and stainless steel.

Therefore, our valves can also be used for applications with aggressive, corrosive or toxic gases (up to a gas purity of 6.0) as well as liquids. We also offer central gas supply units for oxygen, inert gases and flammable gases. Metal membranes are used as standard for our ultra-pure gas systems and ultra-pure gas valves.

In addition to standard equipment in a variety of variants, our offer also includes customer-specific solutions that can be executed according to customer requirements.

What are high-purity gases?

High purity gases are gases with a residual impurity level in the ppm range; this refers to contamination by foreign gases. One ppm corresponds to a residual impurity of 0. 0001 volume in %. The representation of the purity is done in a so-called dot notation (5. 0/5. 5/6. 0 etc. ) for example:

We speak of high purity gases with a gas purity of 5.0 or higher.
