Pressure Gas Needle Valve

In simple terms: A "precision flow control valve" designed to regulate gas flow at high pressure, using a needle-like stem that gradually adjusts the opening to control the flow rate. Think of it as a finely-tuned faucet, giving you perfect control over how much gas flows through your system, all while withstanding high pressures and ensuring no leaks.

• High Pressure Resistance: Maximum working pressure of 345 bar (about the pressure you'd encounter at a depth of 3,450 meters underwater).
• Precise Control: The needle valve's fine-thread stem allows for accurate adjustment of gas flow, ideal for applications requiring subtle, consistent flow rates.
• Flexible Connections: Available with multiple NPT connection sizes (1/8, 1/4, 3/8, 1/2), so you can match it to your system's requirements.
• Leak-Proof: Designed with tight sealing mechanisms to prevent gas leaks and ensure safety in high-pressure environments.

Analogy: Think of it like a precision ink pen-small adjustments with the needle stem let you control the flow with high accuracy, just like writing in fine detail.

• Gas Cylinder Management: Ideal for controlling gas flow in cylinders with pressures up to 345 bar, such as in hydrogen, nitrogen, or oxygen storage systems.
• Industrial Systems: Used to precisely regulate gas flow in machinery or systems requiring high-pressure gas delivery with consistent flow rates.
• Chemical Processing: Ensures accurate flow control in chemical systems where precise regulation is critical, particularly when dealing with non-corrosive gases.
• Laboratories: Perfect for applications where high-purity gases need to be controlled with pinpoint accuracy, ensuring no contamination or excess flow.

Two operation modes:

• Handwheel Version:

1. Suitable for: Situations that require fine control over flow rate (like in laboratories or testing environments).
2. Operation: Rotate the handwheel to move the needle stem, adjusting the flow of gas in precise increments.

• Lever Version:

1. Suitable for: Scenarios where quick adjustments are needed (like in industrial setups).
2. Operation: Pull the lever to open or close the valve, allowing for more immediate changes in flow rate.

• Direction matters: Always ensure the valve is installed in the correct flow direction, which is marked on the valve body.
• Connection matching: Make sure the connection size (e.g., 1/8, 1/4, 3/8, 1/2 NPT) fits your system. Use sealing tape if necessary to prevent leaks.
• Regular inspection: Needle valves are subject to wear over time, especially the needle stem. Check periodically for any signs of damage or leakage.
