Solenoid valves use the electromagnetic principle for automatic regulation of the flow of liquid and gaseous operating substances. They are used in the distribution of water, steam, air, non-aggressive gases, in cooling systems, in aggressive or explosive environments and other applications. A special type of solenoid valve (so-called juice solenoid valves) allows the control of fluid flow through a flexible tube (hose) without the medium coming into contact with the valve body.
Solenoid valves are predominantly two-way, but you can also choose from three and four-way variants with direct or indirect control. They are designed for low-pressure, medium-pressure, and high-pressure equipment. In the event of a power failure, the valve will reset to either the open or closed position depending on its type. Some variants also allow manual control. Solenoid valves feature a wide range of IP protection, making them suitable for use in dusty and humid environments or in applications requiring valve immersion.
Solenoid valves are made from high-quality materials for long-term reliability, functionality, safety, and durability. The valves include a coil, which should be mounted in a vertical position and should not be subjected to excessive long-term load to prevent burning out.

Solenoid Valves are used for shutting off the flow of water, steam, aqueous solutions, oils, or neutral gases. Their primary applications include water distribution, heating and cooling systems, or air conditioning. Some special types of solenoid valves are specifically designed for high-pressure equipment. They operate such that they are closed without voltage or open without voltage. The most commonly used are the classic two-way versions of solenoid valves. However, more complex designs are also manufactured as needed. The inlet and outlet are in commonly used standard threaded designs. The operating temperature, pressure, and other parameters are always specified for each product type.
A solenoid valve can also be equipped with manual control, as is the case with emergency models.
Direct-Acting Solenoid Valves
These are valves where the main plunger is directly connected to the armature (core) of the solenoid, meaning the solenoid directly opens the passage through the valve without the need for a pressure differential. These valves operate from zero pressure differential, but the maximum pressure differential depends on the magnetic force of the solenoid (the larger the valve orifice, the smaller the pressure differential, with the same size solenoid).
Pilot-Operated Solenoid Valves
These are valves where the main plunger is not directly connected to the armature (core) of the solenoid, meaning the solenoid only opens an auxiliary bypass channel (auxiliary seat), which releases the pressure above the main plunger (piston, diaphragm) and opens the passage through the valve with a minimal pressure differential. These valves always operate from a certain minimum pressure differential. When the pressure differential drops below the minimum threshold, the plunger starts to restrict the passage through the valve, but the auxiliary seat remains open even without the need for a minimum pressure differential. To close the solenoid valve, no minimum pressure differential is required; closure is ensured by a spring. With these valves, different valve sizes can be controlled with the same size solenoid because the auxiliary seat controlled by the solenoid always has the same orifice size.
