Double Stage Argon Pressure Regulator

Double stage Argon Pressure Regulator — constant outlet pressure from full cylinder to empty

A Double stage Argon Pressure Regulator places two reduction stages in series, so the outlet pressure stays steady as the cylinder falls from full to nearly empty. REAL GAZ supplies these regulators for jobs where a long argon run must not drift, such as automated welding, laboratory instruments and gas supply panels.
The first stage cuts cylinder pressure to a mid value, and the second stage fine-tunes the outlet for the user.

Regulators are specified to EN ISO 2503 with EN 837-1 gauges, and argon purity can be supplied up to 5.0 or 6.0 grades for industrial and laboratory customers.

With two stages, the first reduces the high cylinder pressure to a fixed intermediate level, often around 20 to 30 bar, and the second drops it to the working value. Because the second stage always sees nearly the same inlet pressure, the outlet is stable regardless of the cylinder content. This is valuable in analytical work, where baseline drift can look like an instrument fault. Double-stage regulators usually cost more than single-stage versions, but the saving in rejected welds, repeated analyses and operator time can justify the investment. We help you decide by reviewing the duration and sensitivity of your process.

🏭 Where Double Stage Argon Regulators Are Used

🤖 Orbital and robotic welding — long unattended runs with constant shielding pressure;
🧫 Analytical instruments — steady argon feed to ICP-OES and similar equipment;
🏭 Manifold and panel systems — a second stage on each line to maintain consistent supply;
🔭 Research facilities — experiments that need repeatable inert atmosphere conditions.

💡 Why Choose REAL GAZ

✅ Stable delivery — minimal supply-pressure effect on the outlet setting;
🧪 Two gauges — inlet contents and outlet pressure are both clearly displayed;
🎯 Precise setting — finer control than a single-stage design;
🔒 Safe design — built-in relief protects downstream equipment from overpressure.
📄 Certificate of Analysis (CoA) — supplied with every order of gas; regulators ship with product documentation.

🔬 Quality Control & Safety

supply-pressure effect is measured on the test bench;
relief valves are checked for set pressure;
gauges are cross-checked against references;
completed units are leak tested and capped, and cylinders are secured upright in use.

Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
