Precision One Inch Lighter Gas Valve for Laboratory and Calibration Equipment with Fine Metering Adjustment

Product Description:

Engineered for applications where exactitude is paramount, our Precision One Inch Lighter Gas Valve is the ideal choice for laboratory burners, analytical instruments, and calibration equipment. This valve functions as an exceptional gas metering valve, offering incredibly fine-thread adjustment to control gas flow with a high degree of accuracy for sensitive pilot flames. Its precision gas valve design ensures minimal hysteresis and repeatable settings, which is critical for consistent experimental or analytical results. The valve body is meticulously machined to prevent internal leakage and provide a smooth, linear flow response. As a specialized laboratory gas valve, it is constructed from materials that resist contamination from high-purity gases. This component is more than a simple shut-off; it is an accurate flow control device that empowers researchers and technicians to maintain the stringent conditions required for their delicate processes, ensuring both safety and precision in every operation.

Bullet Points:

• Excels as a precise gas metering valve for critical flow adjustment applications.

• Its design as a precision gas valve ensures repeatable and accurate flame settings.

• Ideal for use as a dedicated laboratory gas valve in research and development settings.

• Provides accurate flow control for stable and consistent pilot light performance.

• Manufactured from high-purity materials to prevent gas stream contamination.

Specific Application Scenario:
This valve is used to control the pilot gas flow for a Bunsen burner in a university chemistry lab, allowing students to perfectly adjust between a safe, visible safety flame and a hot, invisible heating flame.

Factory Production Floor:
The manufacturing process involves ultra-precise CNC machining of the stem and body to tolerances within microns. Assembly is conducted in a climate-controlled cleanroom to prevent any particulate contamination.

Packing and Transportation:
Each valve is individually wrapped in a lint-free cloth, sealed in an anti-static bag, and placed in a custom-fit foam insert within a box to prevent any damage to the finely threaded stem during transit.

FAQ:

1. How does this valve achieve such fine control as a gas metering valve?

   • It uses a fine-pitch thread on the stem, which allows for very small incremental adjustments with each turn, providing superior control over the gas flow rate.

2. What makes this a precision gas valve compared to a standard one?

   • Beyond fine threads, it features a specially machined needle and seat that provide a linear flow characteristic, meaning the flow rate changes consistently with the handle position.

3. Is this laboratory gas valve suitable for use with specialty gases?

   • Yes, it can be configured with compatible seals (such as PTFE) for use with a variety of specialty and high-purity gases common in laboratory settings.

4. How does it contribute to accurate flow control?

   • The combination of its fine threads and precisely machined components minimizes "dead travel," allowing users to achieve and replicate a specific flow setting with high accuracy.

5. Can the valve be easily contaminated by dirty gas lines?

   • While it is built for clean systems, its design allows for disassembly and cleaning, though we recommend installing a upstream filter in non-laboratory environments.
