Pressure switch LF WB146225

A pressure switch regulates the water pressure in a commercial coffee machine, ensuring the pump delivers the correct flow for espresso extraction. When the machine draws water, the switch senses the drop in pressure and signals the pump to start. Once the target pressure is reached, the switch stops the pump, maintaining consistent brewing conditions without manual adjustment.

The operator does not interact directly with the switch; it works automatically within the machine's hydraulic circuit. Installation involves connecting the switch to the water line and securing its electrical terminals to the machine's control board. Once fitted, the switch requires no further setting—it responds to pressure changes as the machine operates.

This Presostato Piris CE is a direct replacement for Coffee Queen, Crem and Expobar coffee machines. It fits the original mounting points and connects to the existing wiring harness without modification.

The catalogue places it under Coffee Machine Spares, Pressure Controls.
