Technology Leadership: Professional FAQ

Expert FAQs about Natural Gas Pressure Regulator & Accessories

1. What material options are available for the regulator body?

The most common materials are WCB (cast steel), 304 stainless steel, and 316L, each selected based on required strength and corrosion resistance for different gas compositions and site conditions.

2. How is the nominal diameter (DN) determined?

Nominal diameter is defined by pipeline size and expected maximum flow; typical ranges for distribution systems are DN15–DN300 mm, ensuring optimal velocity and minimal pressure drop.

3. What is the function of a shut-off valve in the system?

A shut-off valve, such as the SSDJ-FZ-*F/C-RQZ, acts as a safety barrier, immediately stopping gas flow upon detecting abnormal pressure—either overpressure or loss—requiring manual reset to reopen, thereby ensuring personnel and property safety.

4. Which installation standards must be followed?

Installations must conform to EN 334/14382 (Europe), ANSI B109.4 (US), or applicable GB standards (China) for pressure regulators and safety shut-off devices, with correct orientation, venting, and protective earthing.

5. How does a cyclone separator benefit the regulator system?

Cyclone separators filter particulate and condensate out of the gas stream before it enters the regulator, preventing wear, blockage, or malfunction in delicate pressure-sensing components (source).

6. What is an electric valve, and why is it used?

Electric valves use actuators for remote or automated operation controlled by PLCs or SCADA; they're essential for modern grid management, emergency shut-down, and enabling smart infrastructure (Control Global).

7. How is shut-off accuracy measured and specified?

Shut-off accuracy is the percentage deviation from the set-point at which a valve must close; typically quoted as ±5%, with tighter tolerances indicating a more sensitive device.

Conclusion: Trust & Authority in Gas Equipment Solutions

In the evolving landscape of energy delivery, natural gas pressure regulator systems, combined with advanced shut-off and electric valves, cyclone separators, and innovative technology, remain pivotal for grid safety and process reliability.
