FKM Seal Burkert Solenoid Valve Diaphragm Valve Type 6213 2/2 Way Normally Closed 00221758 00221759 00221761 Port Size G3/8 Orifice 10mm DC24V AC24V AC220V

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 of neutral gaseous and liquid media in industrial automation and process environments. These valves incorporate a spring-coupled diaphragm that aids the opening mechanism, ensuring reliable operation starting from zero bar differential pressure. Additionally, their damped design facilitates quiet closing and reduces noise during operation.

This series is offered as a 2/2-way normally closed configuration (Circuit Function A), featuring port sizes that vary from G3/8 to G1 and orifice diameters spanning 10 mm to 25 mm (DN 10 to DN 25). The variety in orifice sizes provides excellent flow flexibility, accommodating applications ranging from precise small dosing to higher flow needs, with Kv values reaching up to 11 m³/h. The valve bodies come in brass, which is standard and compliant with European drinking water standards, dezincification-resistant brass for alternative markets, and stainless steel for use with aggressive media. Seal and diaphragm options include NBR, FKM (fluororubber), and EPDM, compatible with media temperatures between -30°C and +120°C. Furthermore, the solenoid coils are molded in chemically resistant epoxy for enhanced durability.

The servo-assisted diaphragm design typically requires a minimum differential pressure for full valve opening in its standard liquid version. However, a specialized HP00 variant is available for gas and vacuum applications, allowing the valve to open without any differential pressure. The valves come equipped with robust polyamide or epoxy-encapsulated coils consuming 8 watts of power and supporting a 100% continuous duty cycle. Voltage options include DC24V, AC24V, and AC220V, each with a ±10% voltage tolerance. To optimize energy efficiency during operation, Kick-and-Drop (KD) coils featuring double coil technology are offered. Electrical connections utilize a tag connector conforming to DIN EN 175301-803 Form A (previously DIN 43650), providing IP65 protection when paired with a suitable cable plug. Installation is flexible, allowing mounting in any orientation, though placing the actuator upright is recommended.

Thanks to its modular construction, the 6213 EV series supports versatile installation through a vibration-proof, screw-secured coil system. With its combination of compact design, high flow rates, low power consumption, and diverse material options, this series delivers reliable and leak-tight performance tailored for demanding fluid control tasks.

Features:

The spring-coupled diaphragm design assists the opening process, enabling reliable operation starting from 0 bar differential pressure. This feature ensures smooth and efficient valve actuation under varying pressure conditions.

The valve is configured as normally closed with Circuit function A, providing fail-safe operation to meet stringent process control requirements. This helps maintain safety and prevents unintended flow.

Available port sizes range from G3/8 to G1 with orifice diameters between 10 mm and 25 mm (DN 10 to DN 25). This extensive range accommodates diverse flow needs suited for various applications.

The valve body is offered in brass, including a dezincification-resistant version, and stainless steel. These material options provide excellent corrosion resistance suitable for both neutral and aggressive media.

Seal and diaphragm materials are available in NBR (-10°C to +80°C), FKM (0°C to +120°C), and EPDM (-30°C to +90°C), ensuring broad compatibility with a variety of media.

Despite its compact design, the valve delivers a high flow rate with Kv values reaching up to 11 m³/h, which supports efficient system performance.

A damped design minimizes noise during valve closure, resulting in quieter operation with reduced audible disturbances.

The valve features an anti-waterhammer design that ensures smooth and stable operation to protect the system from pressure surges.

Electrical compatibility includes DC 24 V, AC 24 V, and AC 220 V options with an 8W power consumption, supporting global power supply standards.

Designed for uninterrupted operation, the valve can run continuously without overheating, ensuring reliable long-term performance.

Energy-efficient Kick-and-Drop (KD) coils utilize double coil technology to reduce electrical power consumption during valve operation.

The valve offers IP65 protection rating, making it dust-tight and resistant to water jets when used with appropriate cable plugs according to DIN EN 175301-803 Form A.

A sealed and bolted coil system ensures secure and stable operation even in environments with high vibration levels.

A special HP00 version of the valve is available that opens without requiring differential pressure, making it ideal for gas and vacuum applications.

The valve is suitable for use in drinking water systems when the appropriate materials are selected, complying with necessary approvals.

The valve can be installed in any position, although installation with the actuator upright is preferred to optimize performance and longevity.
