Ensure flawless extraction and protect your espresso machine from damage with the genuine 3-way 90° Solenoid Valve \*W/ 0.8 Gicleur 220V (Part \# B.3.004). This critical electromagnetic component is the heart of your brew group's pressure management system, controlling the flow of water during extraction and rapidly releasing pressure afterward. Key features include its durable construction, a standard 90° elbow connection, and an integrated 0.8mm gicleur (flow restrictor) for precise water delivery consistency. Operating at 220V, this OEM part is engineered to the exact specifications required by commercial espresso machines, guaranteeing a perfect fit and dependable electronic functionality. If you are experiencing issues like a **leaky portafilter after brewing** or **slow pressure release from grouphead**, replacing your solenoid valve with this specific model is the definitive solution.

The primary benefit of this specialized 3-way valve is its ability to immediately vent residual brew pressure to the drip tray once the shot is completed. This action results in a compact, dry coffee puck that is easy to knock out, eliminating the messy, soupy pucks that often indicate a failing valve. By quickly relieving pressure, this component also plays a crucial role in preventing over-extraction, which is essential when troubleshooting **why my espresso tastes bitter or burnt**. Proper function of this 3-way solenoid valve is vital for maintaining shot quality and ensuring a seamless, high-volume workflow. Integrating this official replacement part ensures your machine maintains optimal internal pressure dynamics and consistent hydraulic performance.

Stop asking **why won't my espresso machine release pressure** and invest in the B.3.004 Solenoid Valve. This replacement part acts as a precision regulator, allowing water to flow from the boiler to the brew head during brewing and diverting excess water to the drain port instantly when the cycle stops. This controlled mechanism prevents drips and leaks and protects sensitive components from sustained high pressure. The precise 0.8mm gicleur helps regulate flow, which is necessary when addressing **how to fix inconsistent shot volume** due to turbulent water flow. Depend on this genuine OEM 3-way solenoid valve to restore peak performance, consistency, and a dry coffee puck to your commercial espresso setup.
