It is used for constant proportion control of gas outlet pressure and air control pressure at 1:1

Applicable media: City gas, liquefied petroleum gas, natural gas and non corrosive gas

Adjustment ratio: 10:1

inlet pressure: 200mbar

Environment temperature: - 20 ~ + 60 ℃

Diameter: RP1 / 2 "~ RP2", DN65 ~ DN100

application

When the air pressure changes, the proportional valve changes the gas pressure with the air pressure to obtain the best air / gas mixture ratio. When the furnace pressure fluctuates, the flow rate of gas and air is affected correspondingly, but the mixing ratio of air and gas will not be affected.

characteristic

*The gas inlet pressure shall not exceed the rated maximum pressure (maximum inlet pressure 200mbar)

*The tar content in the gas is less than 20mg / m3. H, 0 < 0.1%

*Set the fire flow through the gas valve and air valve in front of the burner

*Adjust the small fire by adjusting the spring of the proportional valve (normally, it is not necessary to adjust the spring to adjust the small fire): open the black lower cover, adjust the slotted screw, increase it in the "+" direction and decrease it in the direction of "" with the adjustment range of ± 3mbar

*The gas inlet pressure in front of the proportional valve should be greater than the maximum pressure of the maximum air feedback

*Working environment temperature - 15 "℃～ + 60C
