Limited adjustment accuracy and limited applicable media

Limited adjustment accuracy and limited applicable media
Solenoid valves usually only have two states: on and off. The valve core can only be in two extreme positions and cannot be adjusted continuously, so the adjustment accuracy is still limited.
The solenoid valve has high requirements for the cleanliness of the medium. Medium containing granular particles cannot be used. If it is an impurity, it must be filtered out first. In addition, viscous media cannot be used, and the viscosity range of media suitable for specific products is relatively narrow.
