Product Description:
The Burkert 6213 EV series consists of servo-assisted 2/2-way diaphragm solenoid valves crafted to ensure dependable shut-off, dosing, and filling of neutral gaseous and liquid media within industrial automation and process environments. These valves incorporate a spring-coupled diaphragm that assists the opening action, allowing them to operate reliably even at zero bar differential pressure. Their damped construction further guarantees quiet closing and minimizes noise during operation.
Offered in a 2/2-way normally closed configuration (Circuit Function A), this series supports port sizes from G1/4 up to G2 and orifice diameters ranging between 10 mm and 40 mm (DN 10 to DN 40). The broad selection of orifice sizes affords excellent flow versatility, accommodating everything from precise small dosing tasks to larger flow demands with Kv values reaching up to 11 m³/h. The valve bodies are available in brass—which meets European drinking water standards as standard—with an option for dezincification-resistant brass suited for other markets, as well as stainless steel for handling aggressive media. Seal and diaphragm options include NBR, FKM (fluororubber), and EPDM materials, supporting media temperatures between -30°C and +120°C.
The servo-assisted diaphragm system typically requires a minimum differential pressure to fully open in the standard liquid version. However, a specialized HP00 variant is designed specifically for gas and vacuum applications, enabling valve operation without needing differential pressure. These valves feature sturdy coils made from polyamide or epoxy encapsulation, consuming 8W of power and capable of a 100% continuous duty cycle. Available voltage options include DC24V, AC24V, and AC220V with a voltage tolerance of ±10%. To enhance energy efficiency, Kick-and-Drop (KD) coils with dual coil technology are provided to reduce electrical power consumption during operation. The electrical connections are made via cable plugs conforming to DIN EN 175301-803 Form A, achieving an IP65 protection rating when combined with a compatible connector.
Designed with modularity in mind, the 6213 EV series allows flexible installation using a vibration-resistant screwed coil system. The valves deliver high flow rates in a compact form factor, low power usage, and offer a variety of material choices to ensure leak-tight, reliable performance in demanding fluid control applications. Additionally, ATEX-certified versions are available for use in hazardous areas, further extending the applicability of this valve series.
