Product Description:
The Burkert 6213 EV series comprises servo-assisted 2/2-way diaphragm solenoid valves engineered for dependable shut-off, precise dosing, and filling tasks involving neutral gaseous and liquid media. These valves are widely used in industrial automation and various process applications. A key feature is the spring-coupled diaphragm that facilitates the opening process, ensuring reliable operation even at zero bar differential pressure. Furthermore, the valves have a damped design which guarantees quiet closing and minimizes noise during operation.
This series is offered in a 2/2-way normally closed configuration (Circuit Function A). Port sizes range from G1/4 to G2, with orifice diameters varying between 10 mm and 40 mm (DN 10 to DN 40). Such a wide selection of orifice sizes provides excellent flow flexibility, suitable for small dosing tasks as well as applications requiring higher flow rates, with Kv values reaching up to 11 m³/h. The valve bodies are typically made from brass, which meets European drinking water standards, while dezincification-resistant brass versions are available for other markets. For more aggressive media, stainless steel body options are provided. Seals and diaphragms come in various materials including NBR, FKM (fluororubber), and EPDM, allowing compatibility with medium temperatures ranging from -30°C to +120°C.
The servo-assisted diaphragm mechanism normally requires a minimum differential pressure to ensure full valve opening in its standard liquid variant. However, a specialized HP00 version is designed specifically for gas and vacuum applications, capable of opening the valve without any differential pressure. Robust polyamide or epoxy-encapsulated coils, consuming 8W of power, equip the valves and support a 100% continuous duty cycle. Voltage options include DC24V, AC24V, and AC220V, with an acceptable voltage tolerance of ±10%. To further enhance energy efficiency, Kick-and-Drop (KD) coils employing double coil technology are available to reduce electrical power consumption during operation. The valves feature an electrical connection via a cable plug conforming to DIN EN 175301-803 Form A standards, achieving IP65 protection when used with a suitable connector.
Thanks to their modular design, these valves offer versatile installation possibilities with a vibration-proof and securely screwed coil system. They combine high flow rates within a compact form factor, low energy consumption, and a broad range of material choices, delivering reliable, leak-tight performance tailored for demanding fluid control applications. Additionally, ATEX-certified versions are offered for safe use in hazardous environments.
