What is the difference between a solenoid valve and a mechanical valve?
A solenoid valve works using electricity, while a mechanical valve operates by manual or mechanical force. In a solenoid valve, an electric current energizes a coil to create a magnetic field that moves a plunger, opening or closing the valve automatically. This makes solenoid valves ideal for applications where fast and remote control of liquid or gas flow is needed.
On the other hand, a mechanical valve is operated manually using levers, cams, or springs. It doesn’t require electricity and is simple in design, making it reliable for basic flow control. The main difference is automation—solenoid valves are electrically controlled and faster, while mechanical valves depend on manual effort and are used where automation isn’t required.
