Single stage multi-gas regulator — simple, economical pressure reduction
A Single stage multi-gas regulator from REAL GAZ reduces cylinder pressure to the working level in one step, and suits several compatible gases such as nitrogen, argon, helium and compressed air.
Because the design has one reduction stage, it is light, easy to service and economical for tasks where the cylinder is used steadily.

REAL GAZ supplies this regulator according to EN ISO 2503, EN 837-1 and ISO 5145 connections, suitable for general industrial and workshop duty.
A single-stage design works best when the cylinder is drawn down steadily and a small drift in delivery pressure is acceptable. As the cylinder empties, the outlet pressure on any single-stage regulator rises slightly, and operators who need a constant value for hours should consider a double-stage model instead. Typical outlet ranges are 0-4, 0-10 and 0-16 bar, and bodies are made from brass for general gases or stainless steel for aggressive ones. Seats are commonly PTFE or nylon, which suit dry inert gases well, but they should not be used for oxygen unless the unit is marked and cleaned for that duty. Always check the label for gas compatibility, never interchange regulators between oxidising and fuel gases, and replace the unit at the interval set by your safety rules.
🏭 Where Single-Stage Multi-Gas Regulators Are Used
- ⚙️ Pneumatic test stands — nitrogen or air at a fixed pressure operates actuators and checks valves for leaks;
- 🔬 Pressure purging — a single stage handles quick purge cycles on vessels and pipework;
- 🏥 Garage and tyre work — dry nitrogen is delivered from a cylinder at a set inflation pressure;
- 🚀 Teaching laboratories — students operate a straightforward regulator without complex adjustments.
💡 Why Choose REAL GAZ
- ✅ Lower cost of ownership — fewer parts mean cheaper spares and easier maintenance;
- 🧪 Good for steady duty — ideal where the cylinder runs at fairly constant demand;
- 🎯 Several gases, one model — compatible inert gases share the same body when materials allow;
- 🔒 Easy to read — large dial faces show both inlet and outlet pressure at a glance;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- verification of material compatibility with the intended gas;
- seat tightness test at full inlet pressure;
- delivery-pressure check at low, mid and high settings;
- final leak test of all joints and the gauge ports.
Cylinders and fittings comply with ADR / UN transport rules and relevant EN/ISO standards.
