Industrial Solenoid Valve


Solenoid valve is the industrial equipment that adjusts the direction, flow, speed and other parameters of system medium through electromagnetism. Driven by the coil, it can be used at different positions in the control system.

Because of its safety, reliability, applicability and controllability, the solenoid valve is used in many industries and plays an important role in our life.  The commonly used solenoid valve is divided into normally closed type and normally open type. Normally closed solenoid valve means that the gas circuit is disconnected when the coil is not energized, and the normally open solenoid valve means that the gas circuit is open when the coil is not energized. Action principle of normally closed solenoid valve: when the coil is electrified, the gas circuit is connected. Once the electricity of the coil is cut off, the gas circuit will be disconnected, which is equivalent to inching. Action principle of normally open solenoid valve: when the coil is electrified, the gas circuit is disconnected. Once the electricity of the coil is cut off, the gas circuit will be connected, which is also the inching.

Usually select based on the continuous working period: normally closed, normally open or continuous electrifying

1. When the solenoid valve needs to open for a long time, and the duration is longer than the closing period, the normally open type should be selected.
2. If the startup time is short or the opening and closing time are not long, the normally closed type should be selected.
There are usually two ways to connect:
Screwed  Connection: DN15/DN20/DN25/DN32/DN40/DN50
Flanged Connection:DN25/DN32/DN40/DN50/DN65/DN80/DN100/DN150/DN200
