S₂+ О₂ Regulator — corrosion-aware pressure control for reactive gas lines
The S₂+ О₂ Regulator from REAL GAZ is intended for lines that carry sulfur-bearing gas together with oxygen, where ordinary brass regulators can corrode or foul. We offer stainless-steel construction, oxygen-clean preparation and seal materials chosen for compatibility with the media, so the regulator keeps its accuracy through repeated use.
Every application is reviewed individually, because concentration, moisture and temperature determine the right materials.

Selection draws on ISO 11114-1 metal compatibility, EN ISO 15001 oxygen-service cleanliness and EN ISO 2503 regulator practice, for research and process lines.
🏭 Where S₂ and O₂ Regulators Are Used
- ⚙️ Combustion research — controlled sulfur and oxygen feeds support studies of flame chemistry and emissions;
- 🔬 Analyser calibration — reference mixtures reach sulfur analysers through a clean, inert regulator;
- 🏥 Materials testing — corrosion chambers need a repeatable dosed supply of reactive gas;
- 🚀 Chemical pilot plants — small-scale reactors use compact regulators for staged gas feeds.
Because the phrase can describe several arrangements, we begin by confirming whether the lines are separate, mixed or sequential. Sulfur-containing gases such as sulfur dioxide or hydrogen sulfide in nitrogen are often supplied at low concentrations, so surface adsorption and moisture are as important as pressure rating. Oxygen service requires a different level of cleanliness, with no hydrocarbons present.
Where both are needed, we normally recommend a dedicated regulator for each cylinder, joined downstream through suitable check valves and a mixing point. Install gas detectors, ventilate the room, and purge with dry nitrogen before and after use. Keep a written log of regulator service for each gas.
