Examples Wuxi fuel ratio valve VRG-25, air-fuel ratio cases valve VRG-25 Price

Examples Wuxi fuel ratio valve VRG-25, air-fuel ratio cases valve VRG-25 price of the air / gas ratio combustion regulating valve, through the connecting pipe pressure receiving air line, when the air pressure changes, air pressure proportional valve to follow the change of gas pressure, mixing ratio to obtain optimum air / gas. Furnace pressure fluctuations have a corresponding effect on gas and air traffic, but the mixing ratio of air and gas will not be affected. 1. Gas inlet pressure must not exceed the rated maximum pressure (maximum inlet pressure 200mbar). 1. Gas tar content <20mg / m3, H2S <0.1%. 2. Set the fire in front of the gas flow through the burner and air valves. Examples Wuxi fuel ratio valve VRG-25, air-fuel ratio in Example 3. valve VRG-25 Price by adjusting the spring proportional valve to regulate a small fire (normal do not need to adjust the spring to adjust small fire): Open black under cover, adjusting slotted screws to the "+" direction to increase, to the "-" direction to reduce the adjustment range ± 3mbar. 4. Gas inlet pressure proportional valve before the maximum air pressure is greater than the maximum feedback. 1. Working temperature -15 ℃ -60 ℃. 2. Technical parameters 3. * Maximum inlet pressure: 200mbar * air pressure control: 2 ~ 120mbar * range: -10 ~ 60 ℃ 4. air / gas ratio: 1: 1 * Minimum pressure inlet and outlet: 20mabr 10. * maximum pressure inlet and outlet: 150mabr air inlet connection: Rp1 / 4 ° 11. * Fuel: city gas, natural gas, liquefied petroleum gas, non-corrosive gases 12. * Features: inlet pressure compensation, the standard supply, internal tube pulse, the minimum flow adjusting screw, fast gasket, all models are equipped with an inlet / outlet pipe fittings and air connections 13. * Material: aluminum body; the interior is aluminum, just, brass and synthetic materials; NBR pad sheets and O-ring cases Wuxi air-valve VRG-25, air-fuel ratio cases valve VRG-25 price of gas safety relief valve mounted on the valve at the outlet, for protection because of the pressure swells and damage downstream equipment, with ultra- pressure relief and regulation functions. VDG series relief valve 1. Maximum inlet pressure: 1bar 2. Housing: die-cast aluminum 3. Medium: natural gas, liquefied petroleum gas, city gas, non-corrosive gases and air 4. The emission range: 20 ~ 500mbar 5. adapt to temperature : -15 ~ 60 ℃
