Metered Valve with Precise Dosing for Home Coffee Machine Water Path with Anti-Scale

Tailored for home coffee machines (espresso, drip coffee), our Metered Valve provides precise water dosing to ensure consistent coffee extraction quality. This metering valve controls hot water flow (15-250mL/dose) with ±0.5% accuracy—critical for brewing applications such as using 30mL water for 15g espresso grounds.

The valve features an anti-scale coating using nanoscale titanium oxide that prevents calcium carbonate buildup from tap water, eliminating valve blockages that commonly disrupt water flow in coffee machines. Constructed from food-grade 304 stainless steel and BPA-free plastic, it meets FDA food contact standards and ensures no harmful substances leach into coffee.

With a low-friction design supporting 10,000+ usage cycles, the valve matches the service life of home coffee machines. Compatible with 12V/24V coffee machine water pumps, it enables seamless one-click brewing mode switching.
