field instruments, isolation valves, and other components into a single unit. Depending on the configuration, it can be assembled as

a pressure regulating cabinet, metering cabinet, or combined pressure regulating and metering cabinet.

2. This product series offers extensive expansion capabilities and can be optionally equipped with pressure/differential pressure transmitters,

temperature transmitters, valve position sensors, leak detectors, etc. Data acquisition and transmission are accomplished via DARU,

and real-time monitoring of the entire equipment’s operational status, anomaly alerts, and even full lifecycle management are realized through DARU LINK.

3. The product is manufactured and tested in accordance with GB 27791-2020 “Pressure Regulating Stations for Urban Gas” and related standards.
