Product Description:
The Burkert 6213 EV series consists of servo-assisted 2/2-way diaphragm solenoid valves, engineered for dependable shut-off, dosing, and filling tasks involving neutral gaseous and liquid media. These valves are widely used in industrial automation and process systems. A key feature is the spring-coupled diaphragm, which aids the opening process, ensuring reliable function even starting from zero bar differential pressure. Additionally, the valves incorporate a damped design that results in quiet closing and minimizes operational noise.
This valve series is offered in a 2/2-way normally closed configuration (Circuit Function A), accommodating port sizes from G3/8 up to G1, and orifice diameters spanning 10 mm to 25 mm (DN 10 to DN 25). This broad selection of orifice sizes provides excellent flow flexibility—ranging from precise dosing applications to higher flow demands, with Kv values reaching up to 11 m³/h. The valve bodies are available in brass, which complies with European drinking water standards, or dezincification-resistant brass tailored for other markets. For handling aggressive media, stainless steel body options are offered. Seal and diaphragm materials include NBR, FKM (fluororubber), and EPDM, supporting media temperatures from -30°C to +120°C, while the solenoid coils are molded with chemically resistant epoxy for enhanced durability.
The servo-assisted diaphragm mechanism in the standard liquid variant requires a minimum differential pressure to fully open. For gas and vacuum applications, a specialized HP00 version is available, which opens without the need for any differential pressure. The valves come equipped with robust polyamide or epoxy-encapsulated coils consuming 8W of power and capable of 100% continuous duty cycles. Voltage options include DC 24V, AC 24V, and AC 220V, with a tolerance of ±10%. To optimize power efficiency during operation, Kick-and-Drop (KD) coils with advanced double coil technology are offered. Electrical connections use a tag connector conforming to DIN EN 175301-803 Form A (formerly DIN 43650), and when paired with the proper cable plug, the assembly maintains an IP65 protection rating. Installation is flexible; the valve can be mounted in any position, though upright actuator orientation is preferred.
The modular design of the 6213 EV series supports versatile installation options through a vibration-resistant screwed coil system. Combining high flow rates within a compact form factor, low power consumption, and a broad array of material choices, this series guarantees reliable, leak-tight performance even in the most demanding fluid control applications.
