Slow opening and quick closing solenoid valve
Combustion system control solenoid valve series are normally closed fast-opening fast-closing, slow-opening and fast-closing two kinds of gas safety solenoid valves. If there is no current excitation, the airflow channel remains closed under the action of the spring. The valve opens quickly, slowly opens to the initial air flow position, and then opens slowly at an adjustable speed. When the current disappears, the valve closes quickly.
Combustion system control solenoid valve series is suitable for the following cut off of gas and air, as well as adjustment control. Gas burners, atmospheric furnaces, industrial combustion furnaces and all gas equipment using gas solenoid valves. Non-corrosive gases such as gas and air.
Combustion system control solenoid valve series If the gas is corrosive, please specify when ordering.
