Burkert Solenoid Valve Type 6213 2/2 Way NC Servo Assisted Diaphragm Valve

Product Description:

The Burkert 6213 EV series consists of servo-assisted 2/2-way diaphragm solenoid valves, specifically engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media within industrial automation and process control environments. These valves incorporate a spring-coupled diaphragm mechanism that aids the opening process, ensuring reliable operation starting from zero bar differential pressure. Additionally, their damped design contributes to quiet closing actions and minimizes operational noise.

This series is offered in a 2/2-way normally closed configuration, known as Circuit Function A, with port sizes ranging from G1/4 to G2. The orifice diameters vary between 10 mm and 40 mm (DN 10 to DN 40), providing a broad spectrum of flow rates suitable for diverse applications. This flexibility covers everything from small-scale dosing tasks to higher flow demands, supporting Kv values of up to 11 m³/h.

Construction materials for the valve bodies include standard brass that complies with European drinking water standards, dezincification-resistant brass tailored for other markets, and stainless steel designed to handle aggressive media. The seal and diaphragm components are available in NBR, FKM (fluororubber), and EPDM, accommodating media temperatures ranging from -30°C to +120°C.

The servo-assisted diaphragm system typically requires a minimum differential pressure to achieve full valve opening in its standard liquid configuration. However, a special HP00 variant is designed for gas and vacuum applications, enabling valve operation without any differential pressure. These valves come equipped with durable polyamide or epoxy-encapsulated coils that consume 8 watts of power and support a 100% continuous duty cycle. Various voltage options are provided, including DC24V, AC24V, and AC220V, each with a ±10% voltage tolerance.

To further optimize electrical efficiency during operation, Kick-and-Drop (KD) coils utilizing double coil technology are also available. The valves feature electrical connections via cable plugs adhering to DIN EN 175301-803 Form A standards, achieving an IP65 protection rating when paired with appropriate connectors.

Designed with modularity in mind, the 6213 EV series allows flexible installation through a vibration-resistant, screwed coil system. Balancing high flow capacity in a compact footprint with low power consumption and extensive material choices, these valves provide reliable, leak-tight performance suited for demanding fluid control scenarios. Furthermore, ATEX-certified versions are offered for use in hazardous area applications.

Features:

The spring-coupled diaphragm aids the opening process, enabling reliable operation starting from a differential pressure of 0 bar. This innovative design ensures consistent performance even under varying pressure conditions.

The circuit function A offers a fail-safe operation mode, meeting the stringent requirements of process control applications. This configuration guarantees safety and reliability in critical environments.

A wide range of port sizes are available, from G1/4 to G2, alongside orifice diameters ranging between 10 mm and 40 mm (DN 10 to DN 40). These options allow the valve to accommodate a broad spectrum of flow demands.

The valve body is offered in brass, including a dezincification-resistant variant, and stainless steel. These materials provide excellent resistance to corrosion for handling both neutral and aggressive media.

The seals and diaphragms come in multiple materials—NBR (operating temperature from -10°C to +80°C), FKM (0°C to +120°C), and EPDM (-30°C to +90°C)—ensuring compatibility with a wide range of media.

Thanks to its compact design, the valve supports high flow rates with Kv values reaching up to 11 m³/h. This ensures efficient operation within various system requirements.

With a damped mechanism, the valve closes quietly, reducing audible noise for a more comfortable and less disruptive environment.

The valve is available in DC24V, AC24V, and AC220V versions, consuming only 8W of power. This wide voltage range makes it compatible with global power supply standards.

Designed for 100% continuous duty cycle, the valve can operate without overheating, ensuring long-lasting reliability and minimal maintenance requirements.

Equipped with Kick-and-Drop (KD) coils utilizing double coil technology, this option reduces electrical power consumption during valve operation, contributing to energy savings.

When paired with a suitable cable plug according to DIN EN 175301-803 Form A, the valve achieves an IP65 protection rating, making it dust-tight and safe against water jets.

The screwed coil system ensures secure and stable operation even in environments subject to high vibration, preventing coil displacement or damage.

A special HP00 version of the valve can open without requiring differential pressure, making it ideal for gas and vacuum applications.

For use in hazardous areas, explosion-proof variants with ATEX certification are available, ensuring safety and compliance with industry standards.

With appropriate material selections, these valves are certified for use in drinking water applications, meeting stringent health and safety regulations.

The valves can be installed either individually or assembled in manifold configurations, allowing for reduced installation space and enhanced system integration.
