Solenoid valve: Switch control for liquid and gas lines, is a two-DO control. Generally used for the control of small pipes.
Solenoid valve: It can only be used as a switch quantity. It is DO control and can only be used for small pipe control. It is common in DN50 and below pipes, and it is rare.
1. Switch form:
The solenoid valve is driven by the coil and can only be turned on or off. The switching time is short.
2. Nature of work:
Solenoid valves generally have a small flow coefficient and a small difference in working pressure. For example, a general 25-caliber solenoid valve has a smaller flow coefficient than a 15-caliber Electric Ball Valve. The solenoid valve is driven by an electromagnetic coil and is relatively easily damaged by voltage surges. Equivalent to the role of the switch, is the role of opening and closing.
Solenoid valves can be reset by general power failure. For such functions, electric valves require a reset device.
3. Applicable process:
Solenoid valves are suitable for some special process requirements, such as leakage, special fluid media, etc., which are more expensive.
