How to identify solenoid valves Difference from electric valve
When you use solenoid valves and electric valves, do you distinguish them? How should we distinguish?
Solenoid Valve: It is an industrial equipment that uses electromagnetic control. It is an automatic basic component used to control fluids. It is an actuator and is not limited to hydraulic or pneumatic.
Electric valve: The valve is controlled by an electric actuator to open and close the valve.
Solenoid valve: for the switching control of liquid and gas pipelines, is two DO control. Generally used for the control of small pipes.
Motorized Valves: Analog adjustments for pipe media flow in liquid, gas, and wind systems, AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.
Solenoid valve: can only be used as a switch, is DO control, can only be used for small pipe control, common in DN50 and below.
Electric valve: can have AI feedback signal, can be controlled by DO or AO, compared to large pipes and dampers.
The solenoid valve is driven by the coil and can only be turned on or off, and the action time is short when switching.
The drive of the electric valve is generally the use of the motor, the opening or closing action requires a certain amount of time analog, can be adjusted.
Solenoid valves generally have a small flow coefficient and a small difference in working pressure. 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.
The electric valve is generally driven by a motor, which is more resistant to voltage shocks. The solenoid valve is fast open and fast closed. It is generally used in small flow and small pressure, and the electric switch is required in the place where the switching frequency is large.
