E61 Group Infusion Valve Triangular Pin M4 Ø 7×40/35mm

This triangular infusion pin controls the pre-infusion cycle in E61-style brew groups. Designed for Vibiemme, Wega, Astoria CMA, Futurmat-Ariete, and La Pavoni machines, it regulates water flow during the initial wetting phase before full extraction begins. Regular replacement ensures consistent pre-infusion timing and prevents brew group valve malfunction.

Made in Italy from brass with M4 threading and 7mm diameter shank. The 35mm triangular tip design provides precise valve control in E61-compatible infusion assemblies.
