2. Key Advantages for Coffee Equipment 

Normally Closed Fail-Safe: Remains tightly sealed by default when unpowered, ensuring absolute water shut-off and preventing accidental boiler leaks or flooding.

3-Way Pressure Venting: Enables 3-way functionality to vent residual pressure from the group head after extraction, drying the coffee puck for easy portafilter removal.

High Thermal Endurance: Engineered to withstand continuous high temperatures up to 150°C with certified food-grade elastomers guaranteeing zero taste alteration.

Direct-Acting Precision: Operates smoothly from 0 bar pressure differential, ensuring instant opening and closing actuation for accurate brewing and backflushing.

3. Coffee Machine Applications 

Commercial Espresso Group Heads: 3-way normally closed actuation for precise extraction control and post-brew pressure relief.

Boiler & Steam Circuits: Reliable water filling, circuit isolation, and steam valve regulation in multi-boiler systems.

Vending & Home Appliances: High-reliability fluid routing and automatic cleaning/rinsing cycle management.
