Hebei gas solenoid valve gas valve selection quotation technical support service

The gas solenoid valve has the characteristics of simple structure, large flow, long life, safety and reliability. It is applicable to the execution structure of two-position on-off switching for heating and combustion medium pipelines for city gas, liquefied petroleum gas, natural gas and other gases for heating and combustion medium pipelines. It is widely used in gas heat setting and textile setting and dyeing industries. Furnace heating for glass and bulb industries and gas heating automatic control systems for other industries.

This valve is a direct-acting, low-pressure solenoid valve that opens once. The valve port gasket that controls the on-off of the medium is directly connected to the movable iron core through the valve stem.
It can be divided into normally closed solenoid valve and normally open solenoid valve, normally closed solenoid valve according to different switch states when power is off. When power is off, the valve mouth is sealed and cut off by the weight of the armature, sealing spring and medium pressure. The flow path of the controlled medium.
After the solenoid coil is energized, the solenoid valve overcomes the weight of the armature and the force of the sealing spring and the pressure of the medium to suck the movable iron core together with the valve port seal, and opens the valve port, and the controlled medium can circulate.
When the normally open solenoid valve is powered off, the electromagnetic suction force is equal to zero. Under the action of the spring, the iron core and the valve stem are lifted up, the valve is opened, and the medium is circulated. When power is applied, the iron core moves down due to the suction force, the valve stem is pushed, the valve is closed, and the medium is cut off.
