Description

49-N2 Double Stage Double Gauge Nitrogen Gas Pressure Regulator

The 49-N2 Double Stage Double Gauge Nitrogen Gas Pressure Regulator is designed for stable, controlled, and reliable regulation of Nitrogen (N₂) 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 use. The double gauge configuration allows the operator to monitor both cylinder pressure and regulated delivery pressure during operation.

Designed for industrial, laboratory, testing, purging, and process applications, the 49-N2 Nitrogen Gas Regulator provides smooth pressure adjustment and dependable gas delivery where stable Nitrogen pressure control is required.

Key Features

Advantages of Double Stage Regulation

The double-stage design reduces high cylinder pressure progressively through two regulating stages, helping to:

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

How to Use

Before installation, make sure the Nitrogen cylinder valve is completely closed.

Connect the 49-N2 Nitrogen Gas Pressure Regulator securely to the cylinder using the correct Nitrogen-compatible connection. Keep the pressure adjustment mechanism in the released position before opening the cylinder valve.

Slowly open the Nitrogen 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 gas 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: Nitrogen is non-flammable, but it can displace Oxygen in confined or poorly ventilated areas. Always use Nitrogen gas equipment in adequately ventilated environments and follow proper compressed gas handling procedures.
