Principle of solenoid valves {Hydraulics} Making India Employable

Solenoid Valve • The solenoid valve is industrial equipment controlled by electromagnetism. It is an automatic basic element to control the fluid. It belongs to the actuator, but not limits to the hydraulic pressure and pneumatic control. • In the industrial control system, the solenoid valve is used to regulate the direction, flow rate, speed and other parameters of the medium. • The solenoid valve can coordinate with different circuits to realize the anticipated control, with both control precision and flexibility being guaranteed.

The solenoid valve is constituted by the solenoid coil and magnetic core. It is the valve body containing one or several holes. When the coil is get through or cut off with power, the operation of the magnetic core will result in that the fluid passes through the valve body and is cut off, so as to reach the goal of changing the fluid direction. The electromagnetic component of the solenoid valve is constituted by the fixed iron core, movable iron core, coil and so on. The valve body is constituted by the slide valve core, slide valve harness and spring base. The solenoid coil is installed on the valve body directly while the valve body is enclosed in the seal pipe, so as to constitute a simple and compact combination. For internal Training purposes only

Solenoid valves can be found in many different sectors, including: • Water supply • Pressure relief and drainage • Treatment of drinking water • Fuel supply • Waste water treatment • Transport and tank facilities • Purification/ treatment of grey and black • Firing systems • Oil and gas burner control water • Gas chromatography • Machine and plant engineering • Gas mixture regulation • Cooling, lubrication and dosing • Blood analysis instruments • Building services • Control of cleaning processes • Large heating systems, climate control • Safety engineering • Water mains protection and fire extinguishing systems • Compressors For internal Training purposes only
