Non-return valves ensure maximum safety

Technical gases have proven their worth in the treatment of metals in areas such as shipbuilding, construction, automotive engineering and kiln engineering, for many decades

Technical gases have proven their worth in the treatment of metals in areas such as shipbuilding, construction, automotive engineering and kiln engineering for many decades.

However, the use of flammable gases can be dangerous - and this is where non-return valves can protect people and property alike.

What many users and plant managers don't know is that danger lurks wherever different gases are used together.

Reverse gas flows can lead to the creation of dangerous mixtures of gases - frequently with fatal consequences.

Gas supply plants, piping and outlet/extraction points should therefore always be equipped with non-return valves.

As a compact component in distribution pipes, they prevent the transfer of one gas into the path of another.

In this way, these safety devices protect against sudden or even gradual reverse gas flow.

Witt place great importance on careful production and selection of materials, ensuring that our products reach the highest standards.

The non-return valves are characterised by a minimal pressure drop and the highest leak tightness during reverse gas flow.

They can be used with almost all technical gases.

The high quality non-return valve even holds its own against major excesses in operating pressure.

They can be supplied for all rates of flow and can usually be installed irrespective of location.

Thanks to the low opening pressure, they can also be used in gas supplies with a low operating pressure.

Our extensive range of products will be presented at the trade show "Schweissen und Schneiden" (World Trade Fair for Welding Engineering, Joining, Cutting, Surfacing) in Essen in September - Hall 6 Stand 209.
