The Krom gas pressure reducing valve GBF is used to control the inlet pressure of gas and air to meet the normal operation of the burner and achieve heating purposes.
Suitable for various gas media
Suitable for biomethane
Adopting imported pressure compensation design, improving adjustment accuracy
The optimal size design allows for higher gas flow through
The safety diaphragm eliminates the arrangement of the blowing pipeline
Tested and certified by EC
Spring type pressure reducing valve adopts imported pressure compensation and zero pressure cutoff design. Due to the regulating effect of the spring, it can also maintain a constant outlet pressure of the pressure reducing valve in the event of fluctuations in gas flow. Inlet pressure compensation can maintain high control accuracy in the event of inlet pressure fluctuations. Zero pressure cutoff can prevent an increase in pressure behind the valve when there is no gas flow.
According to the requirements specified in EN746-2, in order to prevent pipeline overpressure,
overpressure automatic shut-off valve SAV and safety release valve SBV should be installed upstream and downstream of the gas pressure reducing valve.But if the pressure resistance level of downstream equipment of the pressure reducing valve is higher than
the actual gas pressure in the pipeline before the pressure reducing valve, the above two types of valves can be omitted.. |
