2. Key Advantages for Coffee Equipment 

3-Way Pressure Relief: Enables effective venting of residual pressure from the group head after extraction, preventing coffee puck sogginess and enabling instant portafilter removal.

Secure Flange Connection: Flange-mounted design ensures a compact, highly reliable seal directly onto espresso machine hydraulic blocks, eliminating vibration leaks.

High Thermal Endurance: Built to withstand continuous high temperatures up to 150°C with food-grade sealing options (EPDM/Viton) ensuring complete taste neutrality.

Direct-Acting Precision: Operates smoothly from 0 bar pressure differential, guaranteeing prompt response times for brewing cycles and auto-backflush routines.

3. Coffee Machine Applications 

Commercial Espresso Group Heads: 3-way valve actuation for brewing control and post-extraction pressure venting.

Boiler & Hydraulic Blocks: Flange-integrated water filling and circuit isolation in multi-boiler machines.

Vending & Automated Coffee Centers: Reliable multi-way fluid routing and automatic cleaning/rinsing cycles.
