Solenoid valve SCHAERER Spare Parts 3370079215

A solenoid valve opens and closes the flow of liquids electrically, without moving parts outside the valve body. When the 21 V DC coil is energised, it creates a magnetic field that pulls a plunger inside the valve. The plunger lifts away from the valve seat, allowing water, milk or syrup to pass through the inlet and out of the outlet. When the coil is de-energised, a spring returns the plunger to the seat, stopping the flow instantly. This on-off control is used in beverage machines to start and stop the dispensing of hot water, steam, milk or flavourings at the exact moment the operator presses a button or the machine's programme calls for it.

To use the valve, connect the inlet and outlet pipes to the corresponding ports on the valve body. Secure the connections with the correct fittings to prevent leaks. Wire the coil to the 21 V DC supply provided by the beverage machine. Once installed, the valve operates automatically: the machine's control board sends a signal to the coil, the valve opens, and the liquid flows until the signal stops. No manual intervention is needed during operation.

The valve body is made of PPSU, a high-performance plastic that resists heat, pressure and the chemicals found in water treatment and cleaning agents. The coil is sealed to protect it from moisture and splashes, which are common in a busy café or restaurant environment. The construction is compact, allowing it to fit into tight spaces behind the worktop or inside the machine's cabinet.

The 21 V DC voltage requirement means the valve is designed for low-voltage control circuits, which are standard in modern beverage equipment. This voltage is safe for use in wet areas and allows the valve to respond quickly to the machine's signals. The valve's small footprint and lightweight construction make it easy to install in existing machines without modifying the layout or adding support.

Cleaning is straightforward: disconnect the power before removing the valve for maintenance. Flush the valve with clean water to remove any residue, and inspect the plunger and seat for wear or debris. If the valve is part of a larger system, follow the machine's cleaning programme to ensure the entire circuit is free of scale or build-up. The PPSU material can be cleaned with standard food-safe detergents and does not corrode or degrade over time.

This solenoid valve is a direct replacement for the original part in SCHAERER coffee machines and water systems. It fits models that use the same article number, ensuring compatibility without adjustment or modification.
