Brief introduction of RTZ-0.4BQ gas regulator
RTZ-0.4BQ gas regulator is a direct acting regulator, which uses a toothed lever structure with built-in overpressure safety shut-off valve. It can be widely used in various medium and low pressure non corrosive gas pressure regulation and voltage regulation. Urban medium pressure pipe network regulation is used by gas boiler below 4T. It is the most common gas regulator in coal to gas project, and its performance of regulating voltage and stability are comparable to imported products.
Main characteristics of RTZ-0.4BQ gas regulator
Stable voltage, high circulation capacity;
With safety cutting device, without additional energy, it can use the pressure of the network itself;
The safety cutting device and the built-in safety release device have the advantages of high action precision, fast response, and no need to be equipped with a safety shut-off valve;
Modular design, simple structure, convenient maintenance, can be maintained online.
Main technical parameters of RTZ-0.4BQ gas regulator
Maximum inlet pressure: 0.6MPa;
Outlet pressure setting range: 1.5-50KPa;
