Solenoid Valve

Solenoid valve is an electromechanical device used to control the flow of liquid or gas. It consists of a solenoid, which is a coil of wire, and a movable plunger or valve that is typically made of ferrous material. When an electrical current is applied to the solenoid, it generates a magnetic field that moves the plunger, either opening or closing the valve.

-Flow Control

Solenoid valve can control the flow of liquids or gases in a system. They can either allow or block the passage of the substance by opening or closing the valve.

-On/Off Operation

Solenoid valves act as on/off switches for fluid or gas flow. When the solenoid is energized, the valve opens, allowing flow. When de-energized, the valve closes, stopping the flow.

-Remote Operation

Solenoid valves can operate remotely by an electrical signal. This feature is beneficial for automation and control systems, allowing for efficient and precise management of fluid or gas flow.

-Quick Response

Solenoid valves have a rapid response time, making them suitable for applications where quick and accurate control of fluid flow is essential.
