Negative pressure produced by nozzle imbibe gas and then mix with low pressure air(350~1000mmh2o).Install regulating valve on the gas entrance.Gas supply pressure 100~300mmh2o on the entrance of regulating valve. Air butterfly valve adjust gas capacity. Regulating valve imbibe a certain of gas along with the change of air pressure.

The VM Efficient Mixer Series characteristicWith the function of the air butterfly valve, adjust the combustion gas flow

calorific value of gas: 3600 to 30000Kcal/m³ ,(The calorific value different, the size of the nozzle is  also different).
