Description

49-H2 Double Stage Double Gauge Hydrogen Gas Pressure Regulator

Note: Based on the model code 49-H2, the correct gas should be Hydrogen (H₂), not Carbon Dioxide (CO₂).

The 49-H2 Double Stage Double Gauge Hydrogen Gas Pressure Regulator is designed for stable, controlled, and precise regulation of Hydrogen (H₂) gas from high-pressure gas cylinders to the required working pressure.

Its double-stage pressure reduction system reduces high cylinder pressure in two stages, helping maintain a more consistent outlet pressure even as the cylinder pressure decreases during operation. The double gauge configuration allows the operator to monitor both cylinder pressure and regulated delivery pressure.

Designed for industrial, laboratory, research, and process applications, the 49-H2 Hydrogen Gas Regulator provides smooth pressure adjustment and dependable gas delivery where stable Hydrogen pressure control is required.

Advantages of Double Stage Regulation

The double-stage design provides improved pressure stability by reducing high cylinder pressure through two regulating stages. This helps to:

• Maintain consistent outlet pressure
• Reduce pressure fluctuations
• Provide stable Hydrogen gas delivery
• Reduce the need for frequent pressure adjustment
• Improve control during continuous operation
• Support precision industrial and laboratory applications

How to Use

Before installation, ensure that the Hydrogen cylinder valve is completely closed and that the regulator, fittings, hoses, and connections are specifically compatible with Hydrogen service.

Connect the 49-H2 Hydrogen Gas Pressure Regulator securely to the cylinder using the correct Hydrogen-compatible connection. Keep the pressure adjustment mechanism in the released position before opening the cylinder valve.

Slowly open the Hydrogen cylinder valve and observe the inlet pressure gauge. Gradually adjust the regulator until the required working pressure is displayed on the outlet pressure gauge.

Check all connections for leakage using an approved Hydrogen-compatible leak-testing method before operation.

After completing the work, close the cylinder valve, safely release the remaining downstream pressure, and return the regulator adjustment mechanism to the released position.

Safety Note: Hydrogen is highly flammable and has a wide flammability range. Always keep Hydrogen equipment away from flames, sparks, hot surfaces, and other ignition sources. Use the regulator only in properly ventilated areas and follow applicable compressed gas and Hydrogen safety procedures.
