Oxygen pressure regulators

Industrially, oxygen is mainly used in metallurgy for the production of pig iron and steel, as well as in copper refining. Pure oxygen or oxygen-enriched air serves here on the one hand to achieve high temperatures, on the other hand to freshen up the crude steel, i. e. to remove unwanted admixtures of carbon, silicon, manganese and phosphorus, which are oxidised and separated. Compared to air, pure oxygen has the advantage that no nitrogen is introduced into the melt. Nitrogen has a negative influence on the mechanical properties of steel (see also Thomas process). In chemical processes, oxygen is usually used for the oxidation of various basic materials, such as the olefin oxidation of ethene to ethylene oxide and the partial (partial) oxidation of heavy oil and coal.

Oxygen is also needed for the production of hydrogen and synthesis gas and for the production of sulphur and nitric acid. Other important products produced by oxidation with oxygen are acetylene (ethine), acetaldehyde, acetic acid, vinyl acetate and chlorine.

Different combustion gases (propane, hydrogen, ethin, etc. ) only achieve sufficiently hot and soot-free flames for welding and brazing or melting and forming glass by mixing with oxygen. After heating and ignition, concrete is cut with a (self-burning) oxygen lance or the burning of iron is done by a sharp oxygen jet alone.

Oxygen is also used to represent ozone, as an oxidant in fuel cells and in semiconductor technology. In rocket technology, liquid oxygen is used as an oxidant and abbreviated with LOX (liquid oxygen). In environmental technology, the discharge of oxygen gas frees wastewater more quickly from organic pollutants and toxins by bacteria. In many drinking water plants, the treatment of drinking water with ozone (ozonation) serves for the oxidation of organic substances or, for example, iron and sterilization and can lead to a significantly better cleaning effect of the filter systems.

In our product portfolio you will find the following valves for your oxygen application: bottle pressure regulators, line pressure regulators, battery pressure regulators, relaxation stations, automatic changeover stations, filters and shut-off valves. Especially in the field of technical gases, our product range of dome pressure regulators offers the D, DH and PID* series, as well as our line pressure regulators series L and LH oxygen pressure regulators for high pressures and large flows.
