How does a pneumatic solenoid valve working principle ?
When an electrical current is passed through the solenoid coil, a magnetic field is engendered which causes a ferrous metal rod to move. This is the rudimental process that opens the valve and it works either directly or indirectly on the air.Customarily Closed (N/C), the valve remains closed when the solenoid is not charged. The Pneumatic AIR Solenoid Valve Metalwork 7010022100, Sales support in Bangladesh. It is very use to packaging machine, Washing machine, Frame make mc, cylinder control and Beverage line.
Pneumatic actuation refers to a valve being tripped through the utilization of compressed air (gas). At a particular point in an industrial or manufacturing process, compressed air is relinquished, causing a valve to open or close. The coalescence of solenoids and pneumatics is twofold. Solenoid valves are utilized in pneumatic processes and solenoid valves and pneumatic valves are utilized in cumulation. The amalgamated valve is called a piloted valve. The more astronomically immense solenoid valve is triggered by the more diminutive pneumatic valve. The pneumatic valve can act as an air cylinder contained in a main valve. A pneumatic solenoid valve is additionally referred to as a compressed air pilot valve.
Benefits of Piloted Valves
Pneumatic valves are customarily run by air captured during a precedent or perpetual process. Since they are being used to trigger more immensely colossal valves and aren’t requiring more cost, they are a more frugal economical way to power a solenoid valve. Compressed air can result in astronomically immense forces available to act on another valve and be recycled after its done its job. Its authentic design or footprint is diminutively minuscule, so it doesn’t integrate very much weight to the mechanism.
Types of Pneumatic Solenoid Valves
Valves can be designated as internally piloted or externally piloted. The valves can further be categorized by the number of connections or paths for flow they contain. Externally piloted valves utilize an external source of air pressure. Internally piloted utilize an internal source of air pressure. Two-way piloted valves can be utilized in dust collector systems. An internally driven pilot valve with four-way connections are generally found in pneumatic operations and are acclimated to move double action cylinders. Pneumatic solenoid valves can be designed as stackable.
