Double stage Propane Regulator — constant outlet pressure from full cylinder to empty
A Double stage Propane Regulator from REAL GAZ combines two pressure-reducing stages in a single body, so the outlet pressure remains almost unchanged while the cylinder empties. The first stage drops the cylinder pressure to an intermediate level and the second refines it, which gives the steadiest supply possible from portable propane.
It is the preferred choice for fixed appliances and any task where flame consistency matters.

A single regulator body can contain both stages, or two separate regulators can be fitted in series, one at the cylinder and one near the appliance. The second arrangement is common in long pipe runs, where a high-pressure first stage lets the line use smaller pipe before the final reduction.
REAL GAZ supplies this product according to EN 12864, EN ISO 7291 and related standards, suitable for long-run, installation and precision-heating use.
🏭 Where Double Stage Regulators Are Used
- 🏘️ Fixed LPG systems — homes, cabins and light commercial sites with twin cylinder banks benefit from a regulated, stable low-pressure supply;
- 🏭 Continuous process heating — lines that run for hours need the same flame at the end of a cylinder as at the start;
- 🌡️ Laboratory and calibration heating — stable fuel pressure helps maintain reproducible temperature in test furnaces;
- 🚚 Fleet depots — workshop heaters and washdown boilers keep operating through cylinder changeovers.
💡 Why Choose REAL GAZ
- ✅ No pressure drift — the second stage compensates for the falling inlet pressure;
- 🧪 Sound materials — brass bodies and stable diaphragms keep performance steady over many years;
- 🎯 Appropriate matching — we pair first-stage and second-stage ratings to the demand of the installation;
- 🔒 Protection for appliances — a steady low-pressure supply reduces stress on gas valves and thermostats;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- two-stage pressure calibration and verification;
- outlet stability checks over a falling inlet range;
- relief and vent function inspection;
- comprehensive leak and body integrity tests.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📋 Installation Pointers
- mount the regulator with the vent facing downwards or protected from rain;
- use a changeover valve if two cylinders are connected, so supply continues uninterrupted;
- tighten and test every joint after fitting, then re-test after the first day of use;
- review the system regularly and replace ageing regulators in line with the maker's guidance.
In cold weather the second stage keeps the burner performing consistently even as the cylinder pressure drops. That makes the double stage design popular in mountain areas, open-air workshops and unheated stores across our markets.
