2.Core Performance Benefits 

Thermal Shock Resistance: Built to handle continuous operating temperatures up to 150°C without elastomer degradation or mechanical failure. 

Taste-Neutral Food Safety: Fitted with certified food-grade EPDM and Viton seals that prevent odor transfer and resist chemical scale build-up.  

High-Pressure Integrity: Solid forged brass architecture safely manages pressures up to 16 bar, eliminating structural leaks during intense extraction.

Instant Actuation: Fast-response electromagnetic coils provide split-second opening and closing for accurate shot timing and group head pressure venting. 

 3. Target Applications 

Espresso Group Heads: Precise water delivery and 3-way pressure venting for clean portafilter removal.  

Boilers & Hydronic Blocks: Reliable water refill, level regulation, and closed-loop circuit isolation.  

Steam Wands & Vending Systems: High-pressure steam routing and automated fluid path control.
