Under ambient conditions oxygen is a colorless, odorless gas. It is not flammable, but promotes combustion. The air contains 21 vol% oxygen. Already small amounts of higher oxygen rates increase the burn rate significantly. This can lead to fire ignition of materials. With increased oxygen concentrations, there is an increased risk of fire and explosion!
Especially during opening and closing operations of valves high speeds can occur. At high oxygen concentrations, this can lead to the ignition of plant parts if impurities of any kind are present in the valve together with unsuitable materials or lubricants.
We develop and manufacture two-way and multi-way ball valves for oxygen applications. By choosing the right design and following important regulations when manufacturing our oxygen valves, we can contribute to safe operation when shutting off oxygen plants, even at high temperatures and pressures.
Our oxygen ball valves are used when standard valves reach their limits. Hartmann’s oxygen valves therefore fulfill the following criteria:
One reference for high temperature oxygen service is our delivery to our customer Yara in Germany, where our valves are working at +400°C gastight as shut-off valves.Show reference
