What is an electric solenoid valve?
Electric solenoid valve is a fluid or gas control device relying on solenoid to increase or lower the seat valve. Solenoid works in conjunction with a return spring designed to return the valve to its neutral position when the solenoid is deactivated. This type of valve is set to remotes open and close valves in inaccessible locations, in multi-valve systems, and in proximity to hazardous environment. Solenoid valves only offer fully open or fully closed functions and cannot be used to throttle or gradually control the flow of gas or liquid. The Coils Used in Electric Soloid Valves May Be Rated for Alternating Current (AC) or Direct Current (DC) in and Range of Voltages and Duty Cycle Durations.
solenoids are a very useful and convenient source of remote control of valves to check fluids and gas. The solenoid works on the electromagnetic principle where the electric current passes through a coil that generates a strong magnetic field. SolenoidThe iron metal is attracted by this magnetic force and is pulled into the center of the coil, providing the linear movement required to control the valve. This linear movement is used to raise the valve plug on or off the seats that either open or close the valve. These two operating methods are known as normally open or normally closed.
After activation, the electrical solenoid valve will keep the valve open or closed until the power supply is cut into the coil. At this point, a strong spring that surrounds the solenoid plunger, pulls it back to the neutral position and restores the secondary valve status. The fact that a direct, physical operating action is not required makes an electric solenoid valve ideal for control of fluid or gas flow in inaccessible places or where the environment with high temperatures, hazardous chemicals and gases or movesMachinery equipment for dangerous working conditions.
Electric solenoid valve can only act as an open or closed device and cannot be used to gradually open or close the valve in applications where the throttle function is required. The valves may have coils evaluated for continuous or limited working cycles depending on the intended end use. A wide range of AC and DC voltages is provided, with DC voltage usually ranging from 12 to 24 volts and alternating current varieties from 24 to 600 volts. Electric solenoid valve coils can also be closed in explosion and explosion attachments for dangerous environments.
