Frequently Asked Questions
Q: What gases are compatible with the RTZ1-/0.4Q series?
This series is designed for non-corrosive gases, including natural gas, coal gas, and liquefied petroleum gas (LPG).
Q: Can the RTZ1 regulator be maintained without shutting down the gas supply?
Yes, the RTZ1 series is designed for online maintenance, meaning it can be repaired and maintained without interrupting the gas flow.
Q: How does the fourth-generation cut-off mechanism work?
It utilizes a steel ball brake release system where the cutting film and sliding mechanism are split. Under thrust, the locking sleeve displaces, releasing the steel ball and allowing the spring to cut off the flow immediately.
Q: What are the available connection sizes for this series?
The series is available in three standard specifications: DN25, DN40, and DN50, all utilizing flange connections PN1.6MPa.
Q: Is this regulator suitable for high-rise residential buildings?
Absolutely. It is specifically engineered to meet the pressure regulation and safety requirements essential for high-rise residential environments.
Q: What is the pressure regulation accuracy of the RTZ1 series?
The pressure regulation accuracy grade is AC10/15, with a closing pressure grade of SG20, ensuring highly stable downstream pressure.
