About this product
Product information from the supplier.
The RTJ2-/HL series gas pressure regulator is a high-precision industrial solution engineered for the stable regulation of non-corrosive gases, including natural gas, coal gas, and liquefied petroleum gas (LPG). Built to meet the rigorous GB27790-2020 City Gas Pressure Regulator standards, this axial-flow type regulator ensures consistent downstream pressure delivery, minimizing deviation even under full load conditions for maximum system reliability.
Designed for heavy-duty industrial environments, the HL series features a robust modular construction that simplifies on-line maintenance and extends the equipment's operational lifespan. By integrating a balance valve design and optional silencers for noise reduction, it provides an optimal combination of high-precision control, rapid membrane response, and structural durability, making it an essential component for safe and efficient gas distribution networks.

Frequently Asked Questions
Q: Which gases are compatible with the RTJ2-/HL series regulator?
It is specifically designed for non-corrosive gases, including natural gas, coal gas, and liquefied petroleum gas (LPG).
Q: How do I adjust the outlet pressure of the HL series regulator?
Locate the adjustment screw under the top protective cap. Turn clockwise to increase outlet pressure and counterclockwise to decrease it, making small increments while monitoring the gauge.
Q: What causes "hunting" or pressure fluctuations in these regulators?
Pressure fluctuations (hunting) are typically caused by excessive upstream pressure, flow turbulence, incorrect regulator sizing, or a blocked vent line.
Q: Does the RTJ2-/HL comply with international standards?
Yes, it is fabricated according to the GB27790-2020 standard for city gas pressure regulators and supports ANSI B16.5 flange connections and EN 334 implementation.
Q: What are the signs that a diaphragm needs replacement?
Common signs include failure to maintain set pressure, visible leaks, or a complete lack of response when adjusting the pressure screw.
Q: Is on-line maintenance possible with this model?
Yes, the modular design and simplified structure are specifically engineered to facilitate easier on-line maintenance, reducing system downtime.
