The Burkert 6213EV 00221433 is a high-performance, servo-assisted 2/2-way solenoid valve designed for reliable control of neutral liquid media. As a normally closed (NC) valve, it remains securely shut until electrically energized. This particular model features a durable brass body and NBR seals, making it suitable for a wide range of applications, including water and other neutral fluids. A key feature of the 6213 EV series is its spring-coupled diaphragm, which allows the valve to open and close without a differential pressure, enabling operation from 0 bar. This design also incorporates a soft-closing function to effectively prevent water hammer in pipelines, ensuring smoother and quieter system operation.
