Product Description:
The Burkert 6213 EV series consists of servo-assisted 2/2-way diaphragm solenoid valves that are engineered to provide dependable shut-off, dosing, and filling of neutral gaseous and liquid media. These valves are widely used in industrial automation and various process applications. A notable feature of this series is its spring-coupled diaphragm, which aids the opening mechanism, ensuring reliable function even from zero bar differential pressure. Additionally, the valves incorporate a damped design that contributes to quiet closing and reduces operational noise.
Available in a 2/2-way normally closed configuration (Circuit Function A), the 6213 EV series offers port sizes ranging from G3/8 to G1 and orifice diameters between 10 mm and 25 mm (DN 10 to DN 25). This variety of orifice sizes allows for exceptional flow flexibility, which can accommodate applications from precise small-scale dosing to higher flow demands, with KV values reaching up to 11 m³/h. The valve bodies come in brass as the standard material, compliant with European drinking water regulations. For other markets, dezincification-resistant brass is offered, and stainless steel options are available for more aggressive media. Seals and diaphragms are made from materials such as NBR, FKM (fluororubber), and EPDM, suitable for media temperatures in the range of -30°C to +120°C. Furthermore, the solenoid coils are encapsulated in chemically resistant epoxy for enhanced durability.
The servo-assisted diaphragm design typically requires a minimum differential pressure to achieve full opening in the standard liquid version. However, a special HP00 variant has been developed specifically for gas and vacuum applications where the valve opens without any differential pressure. Robust polyamide or epoxy-encapsulated coils with a power consumption of 8W are used, enabling a 100% continuous duty cycle. Voltage supply options include DC24V, AC24V, and AC220V, all with a tolerance of ±10%. To optimize energy efficiency, Kick-and-Drop (KD) coils incorporating double coil technology are available. Electrical connections are made via a tag connector that complies with DIN EN 175301-803 Form A (previously DIN 43650), which ensures IP65 protection when paired with a suitable cable plug. Installation flexibility is a key advantage, as the valves can be mounted in any position, though upright actuator placement is preferred.
Thanks to a modular design, the 6213 EV series supports versatile installation options along with a vibration-proof, screwed coil system. Combining high flow rates in a compact format with low power consumption and an extensive selection of materials, this valve series delivers reliable and leak-tight performance. It is an excellent choice for demanding fluid control applications where durability and precision are essential.
