Large solenoid SCHAERER Spare Parts 3322737000

A solenoid valve controls the flow of liquids or gases through a hose without manual intervention. In professional beverage equipment, it acts as an electrically operated tap: when power is applied, a magnetic field pulls a plunger away from the valve seat, opening the passage; when power is cut, a spring returns the plunger and seals the seat again. This on-off action allows precise timing of drink dispensing, steam release or water supply in automatic coffee machines, post-mix dispensers and similar appliances.

The operator connects the solenoid in-line with the hose that carries the fluid—water, milk, syrup or steam. A control signal from the machine's programme energises the coil, opening the valve for the exact duration needed to deliver the correct volume. Once the signal ends, the valve closes instantly, stopping the flow. This sequence repeats for each drink cycle, ensuring consistent portioning and preventing drips or overflows.

This SCHAERER hose solenoid is a direct replacement part designed to fit specific models of SCHAERER coffee and beverage machines. It is installed by disconnecting the hose from the existing valve, removing the old solenoid, and securing the new unit in its place with the original fittings. No additional tools or modifications are required beyond those used for the original assembly.

As a spare part, it maintains the original equipment's performance and compatibility with the machine's control systems. It is used where the catalogue lists SCHAERER article 3322737000 as the correct replacement for a failed or worn hose solenoid.
