A Correct Understanding of 2-Way 2-Position Solenoid Valves

Inside a 2-way 2-position solenoid valve there is a sealed cavity; at each position there is a groove, in the center of the groove is a valve, and on both sides there is an electromagnet. When the magnet contacts the valve body, the valve body is subject to the magnet's attraction, so that different outlets can be blocked or leaked according to the movement of the valve body. Therefore, by controlling the current of the normally closed 2-way 2-position solenoid valve, mechanical movement can be achieved.

Working principle of a 2-way 2-position water solenoid valve:

This valve is a pilot solenoid valve of a two-stage opening valve; its structure mainly includes a pilot valve and a main valve, and the main valve uses a rubber seal. In a steady state, the movable iron core seals the inlet of the pilot valve, equalizing the pressure inside the valve chamber and thereby closing the inlet of the main valve. When the coil is energized, a magnetic force is generated that pulls up the movable iron core, causing the liquid in the valve chamber to leak from the pilot valve port and creating a pressure difference, which rapidly expands the valve disc or valve cup, opening the main valve port and forming a passage through the valve. When the coil is cut off, the magnetic field disappears, the movable iron core resets, the pilot valve port closes, and the pressure in the pilot valve and main valve chamber balances, and the valve returns to the closed state.

Features of the pneumatic 2-way 2-position solenoid valve:

The direct-acting valve disc structure is used to achieve pressure-free startup, expanding its application industries.

The platform-type valve disc structure is used for reliable opening and closing, and extends the service life of the product.

The use of a plastic-encapsulated coil improves the safe operation of the product under many conditions.

Working applications of the water-use 2-way 2-position solenoid valve:

Water solenoid valves are suitable for using water or liquid as the working medium, and can mechanically, automatically, or remotely operate the on/off of pipelines carrying water, oil, liquid, and other working media. Because this valve uses a rubber seal, the cleanliness requirement for the working medium is greatly reduced, and it has the characteristics of fast opening and closing and high reliability.
