To achieve (select and apply) an industrial gas regulator correctly, you need to focus on selection, installation, and operation. Here is a clear step-by-step guide:

1️⃣ Define Your Application Requirements

Before choosing a regulator, confirm:

• Gas type (Natural gas, LPG, biogas, etc.)

• Inlet pressure range

• Required outlet pressure

• Maximum flow rate (Nm³/h or m³/h)

• Operating temperature

• Indoor or outdoor installation

• Required standards (CE in Europe, especially in Germany)

2️⃣ Select the Correct Regulator Type

✔ Direct-acting regulator

• Simple structure

• Suitable for small/medium flow

• Fast response

• Lower cost

✔ Pilot-operated regulator

• High flow capacity

• More stable outlet pressure

• Better for industrial combustion systems

If you are using it for burners or thermal systems, pilot-operated types are usually more stable.

3️⃣ Check Important Technical Parameters

• Pressure rating (PN16 / PN25 etc.)

• Flow coefficient (Kv or Cv value)

• Connection size (DN25, DN50, etc.)

• Material compatibility (body: cast iron, steel, stainless steel)

• Built-in safety shut-off valve (SSV) if required

4️⃣ Choose Reliable Brands (Optional but Recommended)

Common industrial regulator manufacturers:

• Emerson (Fisher regulators)

• Honeywell

• Dungs

• Kromschröder

Madas

5️⃣ Proper Installation

To achieve good performance:

• Install gas filter before regulator

• Install pressure gauge before and after

• Keep straight pipe section (5D upstream recommended)

• Avoid vibration

• Ensure correct flow direction

6️⃣ Commissioning & Adjustment

• Slowly open upstream valve

• Adjust spring setting screw gradually

• Check outlet pressure stability

• Perform leak test

• Test safety devices (if equipped)

7️⃣ Regular Maintenance

• Check diaphragm condition

• Clean internal filter (if any)

• Inspect pressure stability

• Calibrate annually

✅ Simple Summary

To achieve an industrial gas regulator successfully:

1. Match gas + pressure + flow

2. Choose correct type (direct or pilot)

3. Install properly

4. Adjust carefully

5. Maintain regularly

   Industrial Gas Regulator – Usage Guide

   An industrial gas regulator is used to reduce high inlet gas pressure (from cylinder or pipeline) to a stable, safe working pressure for burners or equipment.

   1️⃣ Main Function

   Reduce high gas pressure

   Maintain constant outlet pressure

   Protect downstream equipment (burner, valves, gauges)

   Improve combustion stability

   2️⃣ Installation Steps
   ✔ Position

   Install vertically (recommended)

   Follow the flow direction arrow

   Keep away from vibration and high temperature

   ✔ Before Installation

   Clean the pipeline (no dust or welding slag)

   Check gas type (Natural gas, LPG, biogas, etc.)

   Confirm pressure range matches system requirement

   ✔ Safety Devices (Recommended)

   Install a shut-off valve before regulator

   Install a gas filter before regulator

   Install a pressure gauge before and after regulator

   3️⃣ Start-Up Procedure

   Close downstream valve

   Slowly open upstream gas valve

   Adjust regulator screw/knob clockwise to increase outlet pressure

   Monitor outlet pressure gauge

   Slowly open downstream valve

   ⚠ Always adjust slowly to avoid pressure shock.

   4️⃣ During Operation

   Check for pressure fluctuation

   Listen for abnormal noise

   Check for gas leakage (use soap water test)

   Keep ventilation good

   If outlet pressure is unstable:

   Check gas filter

   Check inlet pressure stability

   Inspect diaphragm and spring inside regulator

   5️⃣ Maintenance

   Clean filter regularly

   Check diaphragm every 6–12 months

   Replace damaged seals

   Calibrate pressure gauge yearly

   6️⃣ Common Problems
   Problem Possible Cause
   Outlet pressure too high Diaphragm damaged
   No pressure output Inlet valve closed / blocked filter
   Pressure fluctuates Inlet pressure unstable
   Gas leakage Seal worn
