Electric valves use electric actuators to control valves to open and close the valves. Electric valves are also called air conditioning valves. Solenoid valve is an industrial equipment controlled by electromagnetism. It is a basic component of automation used to control fluids and is an actuator. So. What is the specific difference between electric valves and solenoid valves?

- Working principle
The electric valve uses the power provided by the motor as energy and has three states: open, closed, and half-open. The solenoid valve also uses electricity as the energy source, but uses a motor to drive the solenoid coil to open and switch. After the solenoid coil is energized, it generates magnetic attraction that overcomes the pressure of the spring and drives the valve core to move. The solenoid valve has a simple structure, but it can only achieve two states of switching.
2.Industrial use
Electric valve: used for analog regulation and AI control of pipeline media flow in liquid, gas and air systems. In the control of large valves and air systems, electric valves can also be used for two-position switch control.
Solenoid valve: used for switch control of liquid and gas pipelines. It is a two-position DO control and is generally used for the control of small pipelines.
- Process requirements
Solenoid valves have some special process requirements during the production process. Because the solenoid valve has many functions, such as flow diversion, adjustment and other functions, the requirements for the sealing and pressure resistance of the medium are relatively high, so the cost is higher.
The function of the electric valve is relatively simple, mainly playing a regulating function in the system, so the cost is relatively cheap.

Selection and Sizing Considerations
Rotary screw machines dominate continuous-duty industrial use, while piston machines suit intermittent, lower-flow tasks. Oil-free technologies safeguard sensitive processes; oil-lubricated designs are economical where air purity is less critical. Compare discharge pressure, output flow, motor power, and footprint before selecting a specific model.
Frequently Asked Questions
What is the main advantage of a screw compressor?
It delivers continuous, stable air flow with low vibration and is ideal for round-the-clock industrial operation.
When is a reciprocating compressor the better choice?
For intermittent use, high-pressure applications, or lower initial budgets, piston compressors remain a practical option.
What does two-stage compression enhance?
Two-stage compression reduces the compression ratio per stage, improving efficiency and lowering discharge temperature.
