The working principle of direct-operated or direct-acting solenoid valves is very simple.What is a direct operated (direct acting) solenoid valve? The four-way valve has four ports, two outlet ports, and two exhaust ports or vents. The three-way valve has three ports, two outlet ports, and one exhaust port or vent. The two-way pneumatic valve typically has two ports one for the instrument air inlet and the other one for the instrument air outlet. The valves in their simplest form have three types mainly, 1. Solenoid valves are often used in pneumatic control to activate the control valves and actuators. Solenoid valve configurations and ratings: The construction provides a compact and leak-tight assembly. This core is enclosed and is made free to move in a permanently sealed tube inside the solenoid coil. These solenoid valves have a solenoid that is mounted directly on the valve body with the solenoid core attached to the valve stem. The de-energized solenoid B, this valve gets closed when there is no electric current through the solenoid that is the valve gets de-energized preventing instrument air supply from passing through it, and the air is vented out to the atmosphere through the exhaust port of the solenoid valve. The energized solenoid A, this solenoid valve opens when an electric current is passed through the coil allowing the instrument air supply to pass through the coil. In the above figure “Working of Solenoid” Which is drawn into the solenoid when an electric current is passed through the coil. This solenoid valve is opened or closed by the movement of the electromagnetic coil with a plunger arrangement. A valve with an orifice where the disc or plug is positioned to allow or stop the flow of air in it.The solenoid is an electromagnetic coil with a plunger arrangement.
The solenoid valve is composed of two basic functional units. What are the functional units of the solenoid valve? The typical solenoid control voltages are 12V DC, 24V DC, 120V AC, or 240V AC.Solenoid-operated valves use an electrical coil to control the position of a poppet, plunger, or spool to open or close a valve.These terms refer to their normal states without a power supply being applied.The two-way valve can be either a normally opened valve (NO) or a normally closed valve (NC).This valve switches an instrument air supply between the two outlet ports.
