RTZ1GQ Gas Pressure Regulator China Factory and Suppliers for High Pressure Systems
The RTZ1-/GQ Series Gas Pressure Regulator is a high-performance, direct-acting industrial solution engineered for medium to high-pressure gas systems. Specifically designed for critical applications such as CNG tankers, small-scale LNG supply points, and urban gas station distribution networks, this series excels in reducing high inlet pressures (up to 6.4 MPa) to stable, safe downstream levels (0.05–1.0 MPa). Its fail-open design ensures maximum safety and reliability in demanding industrial environments.
Built to the rigorous GB 27790-2020 standards, the RTZ1-/GQ series features a sophisticated fifth-generation trip-brake release cut-off mechanism, providing rapid response times of ≤1s. This ensures immediate gas flow cessation during overpressure events, protecting downstream equipment and personnel. With its compact footprint and modular design, it allows for efficient online maintenance, reducing downtime and operational costs for gas distribution infrastructure.

Frequently Asked Questions
Q: What are the main applications for the RTZ1-/GQ series?
These regulators are primarily used in medium to high-pressure gas systems, such as CNG tankers, small-scale LNG users, and urban gas station distribution networks for pressure reduction and stabilization.
Q: How do I adjust the outlet pressure on an RTZ1-/GQ regulator?
Remove the cap screw and turn the internal adjustment screw clockwise to increase outlet pressure or counter-clockwise to decrease it. Always use a downstream pressure gauge for precise calibration.
Q: When should I replace my gas pressure regulator?
Replacement is recommended if you notice unstable outlet pressure, frequent safety trips, visible corrosion, or if the diaphragm and seals have degraded due to long-term service in harsh conditions.
Q: Does the RTZ1-/GQ series comply with international safety standards?
Yes, the product is manufactured according to the GB 27790-2020 City Gas Pressure Regulators standard, ensuring high safety and reliability.
Q: What is the response time of the safety shut-off valve?
The safety shut-off valve features a high-response trip-brake release mechanism with a response time of ≤ 1 second.
Q: Which gases are compatible with this regulator?
It is suitable for Natural Gas, coal gas, Liquefied Petroleum Gas (LPG), and other non-corrosive gases.
