System features:

a. Equipped with safety measures such as ultra-high/ultra-low pressure cut-off valves, safety relief valves, and restrictions on excessive gas usage;

b. The equipment undergoes pre installation and ventilation testing before leaving the factory, and all control points are set according to the preset values required by the user;

c. Suitable for natural gas, artificial coal gas, liquefied petroleum gas or mixed gas, etc., with easy replacement of gas types;

d. Adopting a 120% flow design, the main and auxiliary circuits can achieve automatic switching function, ensuring uninterrupted downstream gas supply and high reliability;

e. High voltage regulation accuracy: ± 2.5% or ± 1%.

The regional pressure regulating cabinet is equipped with ultra-high/low pressure automatic cut-off devices and safety relief devices to ensure that the outlet pressure value is automatically maintained within a certain range with changes in gas consumption and fluctuations in inlet pressure. The regional pressure regulating box can be equipped with high-precision flow meters, and all products undergo airtightness testing before leaving the factory. Its control points are strictly set according to user requirements to ensure simple and convenient on-site operation. According to user requirements, the box can be equipped with insulation, the pipeline can be electrically traced, and the system can be remotely controlled.

Typical performance examples: Over 100 units in the North China Petroleum and Gas Department, over 60 pressure regulating boxes in Changping and Liaocheng regions of Xinao Group, over 30 units in Lanzhou Carbon Group, over 40 units in Huangshichengtou, over 80 units in Antai, Ezhou, over 30 units in Huayou, Zhuozhou, and over 50 units in Yumen Oilfield.
