Small regulator for big requirements

Engineer Live News Desk

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

This makes the high-quality fittings ideal for all applications with high demands on accuracy, e.g. for analysis technology, for sampling and dosing as well as for small burner systems or as pilot pressure regulators. Both in-line and panel mounting are possible. For medical applications, Witt also supplies the Mini with FDA-approved elastomers.

Designed and cleaned for oxygen in accordance with EIGA and CGA.

An outstanding feature is the explicit suitability for use with oxygen. Witt has designed the Mini pressure regulators specifically for oxygen (per EIGA 13/20 and CGA G-4.4) and, unlike the 'compressed air' regulators commonly available on the market, uses elastomers that are proven to be resistant to oxygen. In addition, the fittings are much more than just free of oil and grease. All components are subjected to a double, elaborate cleaning process in accordance with EIGA 33/18 and CGA G-4.1. The Mini series thus offers the highest level 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 to 3, 10 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.
