Burkert 00221678 00221679 00221681 00221610 00221611 00221613 Chemical Corrosion Resistant FKM Seal 2/2 Way Diaphragm Brass Solenoid Valve 6213 Series G1/4 Internal Thread

Product Description:

The Burkert 6213 EV series comprises servo-assisted 2/2-way diaphragm solenoid valves, engineered to provide dependable shut-off, dosing, and filling functions for neutral gaseous and liquid media within industrial automation and process applications. These valves incorporate a spring-coupled diaphragm that facilitates the opening operation, ensuring reliable performance starting from 0 bar differential pressure. Additionally, the damped construction guarantees quiet closing action and minimizes operational noise.

Available in a 2/2-way normally closed configuration (Circuit Function A), the series supports port sizes ranging from G1/4 up to G2, and features orifice diameters between 10 mm and 40 mm (equivalent to DN 10 to DN 40). This broad selection of orifice sizes enables exceptional adaptability in flow rates, catering to small dosing tasks as well as higher flow demands, with Kv values reaching up to 11 m³/h. The valve bodies are manufactured from brass as standard—complying with European drinking water standards—with options for dezincification-resistant brass suited for other markets, and stainless steel available for more aggressive media. Seals and diaphragms come in various materials, including NBR, FKM (fluororubber), and EPDM, allowing compatibility with media temperatures from -30°C to +120°C.

The servo-assisted diaphragm mechanism typically requires a minimum differential pressure for full valve opening in the standard liquid model. However, a specialized HP00 variant exists for gas and vacuum applications that operates without the need for differential pressure, opening the valve reliably under these conditions. Equipped with robust polyamide or epoxy-encapsulated coils consuming 8W, the valves support a 100% continuous duty cycle. Voltage options include DC 24V, AC 24V, and AC 220V, with a tolerance of ±10%. To enhance energy efficiency during operation, Kick-and-Drop (KD) coils featuring double coil technology are also offered. The electrical connection utilizes a cable plug compliant with DIN EN 175301-803 Form A standards and achieves IP65 protection when paired with an appropriate connector.

Designed with modularity in mind, the valves allow for flexible installation through a vibration-proof, screwed coil system. Combining high flow capacities in a compact form factor, low power requirements, and diverse material choices, the 6213 EV series ensures reliable, leak-tight operation for challenging fluid control environments. For applications in hazardous areas, ATEX-certified variants of the valves are also available.

Features:

The spring-coupled diaphragm supports the opening process, enabling reliable operation even at zero bar differential pressure. This innovative design enhances performance and ensures smooth functionality under varying pressure conditions.

Equipped with Circuit Function A, the valve provides fail-safe operation tailored for process control applications. This configuration guarantees safety and stability by maintaining a normally closed state when not energized.

The valve is available in port sizes ranging from G1/4 to G2, along with orifice diameters between 10 mm and 40 mm (DN 10 to DN 40). This broad selection allows for matching diverse flow requirements across various systems.

Multiple body materials are offered, including brass with a dezincification-resistant option and stainless steel, providing excellent corrosion resistance for both neutral and aggressive media. Additionally, various seal and diaphragm materials are available such as NBR (-10°C to +80°C), FKM (0°C to +120°C), and EPDM (-30°C to +90°C), ensuring broad media compatibility.

Featuring a compact design, the valve delivers high flow rates with Kv values up to 11 m³/h for efficient system operation. Its damped design also enables quiet closing, reducing audible noise and enhancing the overall user experience.

Available in multiple voltages including DC24V, AC24V, and AC220V with a power consumption of 8W, the valve is compatible with global power supplies. It supports a 100% continuous duty cycle for long-term reliability without overheating. An energy-saving option with Kick-and-Drop (KD) coils utilizing double coil technology helps reduce electrical power consumption during operation.

The valve boasts IP65 protection, making it dust-tight and resistant to water jets when used with an appropriate cable plug according to DIN EN 175301-803 Form A. Its vibration-proof screwed coil system ensures secure operation even in high-vibration environments. Furthermore, an HP00 variant is available, which opens without differential pressure, suitable for gas and vacuum applications.

Explosion-proof ATEX certified versions are offered for hazardous area applications, while certain models have approvals for use with drinking water, contingent on material selection. The valve supports modular installation options, allowing it to be mounted either individually or in manifold assemblies, thus optimizing installation space.
