What Is An Electromagnetic Drive Valve?

Electromagnetic driven valve refers to the valve that uses the magnetic field generated by the electromagnetic coil to drive the switch of the valve. When the current passes through the electromagnetic coil, a magnetic field is generated, which creates a magnetic force on the iron core, thereby pushing the valve core to move and controlling the on-off and flow of fluid.

The electromagnetic drive valve is usually composed of a power supply, a control circuit and an actuator. Through the control circuit to apply current to the actuator, thereby generating a magnetic field, driving the movement of the valve core, control the fluid on and off and flow.

Specifically, in some Marine systems with a high degree of automation, such as the ship's fuel supply system, hydraulic control system, seawater cooling system, etc., electromagnetic drive valves are needed to control the on-off and flow of liquids. These electromagnetic drive valves are usually composed of electromagnetic coils, valve bodies, spool, etc., which adjust the magnetic field strength by controlling the size of the current, so as to control the movement of the spool, and realize the control of liquid on-off and flow.

In addition, on some special purpose ships, such as ocean engineering ships, scientific research ships, etc., electromagnetic drive valves also need to be used to meet special needs. For example, the ballast water system on an offshore engineering ship needs to use an electromagnetic drive valve to control the injection and discharge of ballast water; The sampling system on a scientific expedition ship requires an electromagnetic drive valve to control the switch of the sampler and the flow of the liquid.
