XINGYU 2W solenoid valve,Namur valve,Pulse valve

Solenoid valve : for liquid and gas pipeline switch control, is two DO control. Generally used for small pipe control. Electric valve: for liquid, gas and wind system pipe medium flow analog regulation, is AI control. In the control of large valve and wind system can also use electric valve to do two switch control. Solenoid valve: can only be used as switching quantity, is DO control, can only be used for small pipe control, common in DN50 and below pipe. Electric valve: can have AI feedback signal, can be controlled by DO or AO, more commonly seen in large pipelines and wind valves.

Bistable solenoid valves  power supply pulsating 120V direct current, can be positive or negative. When the pulsating dc voltage of different polarity is applied to the solenoid coil, the spool will move in different directions. When power is stopped, the spool will stop at the end of the movement. There is only body and coil inside the  bistable solenoid valve , so the volume is smaller than that of unistable solenoid valve. In addition, when the spool is in any state, no power is required, so the power consumption is very small.
