Frequently Asked Questions
Q: Which gases are compatible with the RTJ2-GK series regulator?
This series is specifically designed for non-corrosive gases, including natural gas, coal gas, and liquefied petroleum gas (LPG).
Q: What makes the "fail-closed" feature important for valve manufacturing?
Fail-closed means that in the event of a power loss or system failure, the regulator automatically shuts off the gas flow to prevent accidents and leakage.
Q: Can the RTJ2-GK be maintained without stopping the gas supply?
Yes, the RTJ2 series supports online maintenance, significantly reducing downtime and operational losses for industrial users.
Q: What production standards does this gas pressure regulator meet?
The product is manufactured according to the GB 27790—2020 standard for City Gas Pressure Regulators, ensuring high reliability and safety.
Q: What is the range of the inlet and outlet pressures?
The inlet pressure (P1) ranges from 0.1 to 0.8 MPa, and the outlet pressure (P2) is adjustable between 50 and 400 KPa.
Q: How does the 5th-generation cut-off mechanism improve safety?
It utilizes a trip brake release form which provides higher response sensitivity and a more reasonable structural design, ensuring faster shut-off during emergencies.
