Valve with manual switch

What is a shut-off or throttle valve

This is a mechanical component that manually or via a lever regulates or completely shuts off the flow of water or steam in a coffee machine's circuit. It is used at the water inlet, when feeding the boiler, or during steam dispensing, allowing the operator to control the amount of medium passing through.

Typical signs of wear

• Water or steam leaks even when the valve is in the closed position
• The lever or knob is hard to turn, sticks, or is loose
• Flow cannot be precisely regulated, the coffee machine does not build pressure correctly
• Drops of water or traces of limescale appear around the valve

Why replace this part in time

A leaking or stuck valve causes inaccurate dosing of water or steam, which affects the quality of the coffee and can lead to greater water leakage inside the machine. Timely replacement prevents damage to surrounding components and keeps the coffee machine running safely.

How to choose the right part

Valves differ in size, type of control, and placement in a specific coffee machine, so before purchasing, verify the exact match using the compatibility table on the product page.
