Witt-Gasetechnik Mini pressure regulators for oxygen

With the latest Mini pressure regulator series from Witt-Gasetechnik, small flow rates can be controlled precisely. The compact pressure regulators can be used for oxygen and carbon dioxide, for fuel gases such as hydrogen, methane or propane, and for technical gases and compressed air.

The fittings are suitable for applications with high demands on accuracy, eg, for analysis technology, and for sampling and dosing, as well as for small burner systems or as pilot pressure regulators. Both in-line and panel mounting are possible.

One feature is that they are explicitly suitable for use with oxygen. Witt has designed the Mini pressure regulators specifically for oxygen (per EIGA 13/20 and CGA G-4.4) and uses elastomers that are proven to be resistant to oxygen. In addition, all components are subjected to a double cleaning process in accordance with EIGA 33/18 and CGA G-4.1 to offer high levels of safety in oxygen applications.

The spring-loaded mini pressure regulators are optionally made of brass or stainless steel and have G 1/8″ connections. The maximum inlet pressure is 25 bar, and three pressure ranges can be selected for the outlet pressure: 0.5–3 bar, 10 bar or 16 bar. The regulators can be used in a wide temperature range from -30°C to +60°C. Two versions are available: non-relieving or relieving with secondary venting. A pressure gauge is available as an option.
