Adjustable Nitrogen flow regulator — set and read nitrogen flow with confidence
The adjustable nitrogen flow regulator from REAL GAZ pairs a nitrogen pressure reducer with a flowmeter, so operators can see exactly how much gas is being used. This avoids waste and gives more repeatable results than pressure alone.
Flow tubes are scaled for nitrogen, and needle valves let operators dial in the desired rate.
Flow tubes are scaled for nitrogen, and needle valves let operators dial in the desired rate.
Flow indicators relate to ISO 5167 principles and the regulator body to EN ISO 2503, supporting industrial and laboratory tasks.
🏭 Where Adjustable Nitrogen Flow Regulators Are Used
- 🍷 Wine and beverage tanks — blanketing with a measured nitrogen flow protects against oxidation;
- 🔬 Sample evaporation — a constant, gentle stream concentrates samples evenly;
- 🏭 Heat treatment — furnace atmospheres need a defined nitrogen flow rate;
- 🧰 Leak and purge tests — technicians control flow while purging pipework.
💡 Why Choose REAL GAZ
- ✅ Visible flow — a scaled tube displays litres per minute;
- 🧪 Reduced consumption — avoid over-purging and save gas;
- 🎯 Fine needle valve — smooth setting from low trickle to full rate;
- 🔒 Rugged guard — protected flow tubes reduce breakage risk;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- flowmeter scale check;
- leak testing;
- pressure rating test;
- inspection of needle valve and seat.

📦 Specifications & Handling Notes
- 📦 Typical ranges — 0–5, 0–15 and 0–60 L/min;
- 🧰 Outlet — hose tail, fir tree or threaded nozzle;
- 🔧 Body — brass or stainless steel;
- 🗂️ Reading — view the ball or float at eye level and keep the tube upright.
When purging a vessel, a common rule of thumb is to pass several volumes of nitrogen through it to bring oxygen down to a low level. A visible flow reading makes this practical, because the operator can calculate the purge time from the vessel volume and the set flow. This approach reduces both the gas used and the time spent on each purge cycle compared with guesswork.
Flow rate varies with downstream back-pressure, so a reading made with the line open to atmosphere will change once a restrictive component is connected. Set the flow with the system in its operating condition and recheck after any change to filters, nozzles or tubing length. For critical processes consider a mass flow controller downstream, with this regulator providing the stable supply pressure it needs.
