Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve that utilizes servo-assisted technology. Available in sizes up to DN 50, this valve operates based on a servo-assisted principle, which allows it to function with a minimal differential pressure. This feature makes it possible to control large flow rates efficiently while maintaining a compact and energy-saving coil system.
The valve body of the Type 6281 comes in several material options to suit different media and comply with international standards. These materials include standard brass that meets European drinking water regulations, dezincification-resistant brass, and stainless steel. This variety ensures the valve can be used reliably in various industrial environments around the world.
Equipped with integrated energy-saving "Kick and Drop" electronics featuring double coil technology, the Type 6281 guarantees dependable valve opening. This innovative design significantly lowers power consumption during operation. Additionally, the valve’s construction is vibration-resistant and offers quiet, damped closing.
For added flexibility, the valve includes an optional manual override. Thanks to its combination of efficiency, durability, and reliable performance, the Bürkert Type 6281 is an excellent choice for industrial automation applications where long service life and consistent operation are critical.
Features:
Servo-Assisted Operation
The system leverages line pressure to actuate the diaphragm, enabling reliable control of large flow rates up to DN 50. This is achieved while maintaining a compact design of the solenoid, ensuring efficiency and space-saving installation.
Energy-Saving Double Coil Technology
Featuring the innovative "Kick and Drop" (KD) technology, this variant employs a high-power pulse for rapid and positive valve opening. Subsequently, a low-power hold reduces energy consumption and ensures the coil remains cool during operation, enhancing overall efficiency.
Robust & Quiet Design
The coil system is centrally screwed to secure a stable electrical connection, providing exceptional resistance against vibration and shock. This robustness contributes to the durability and reliability of the device.
Additionally, an optimized pilot circuit combined with a damping mechanism allows for soft and quiet closing. This design minimizes water hammer effects and operational noise, creating a smoother and quieter performance.
Versatile Materials & Certifications
The product is available in various body materials including Brass and Stainless Steel. The standard brass variant meets the European drinking water standards, ensuring safety and compliance.
For use in hazardous environments, explosion-proof versions are offered with ATEX and IECEx certifications, providing enhanced safety in potentially explosive atmospheres.
Easy Maintenance & Commissioning
An optional manual override feature is available to facilitate straightforward testing, maintenance, or emergency operations in the event of power failure. This capability ensures continued usability and serviceability.
Long Service Life
A broad selection of diaphragm materials such as NBR, EPDM, and FKM guarantees compatibility with various media types. This versatility secures long-term sealing integrity and extends the overall lifespan of the product.

Support and Services:
Burkert Solenoid Valves are precision-engineered devices designed for reliable fluid control in a wide range of industrial applications. To ensure optimal performance and longevity of your Burkert solenoid valve, it is important to follow proper installation, operation, and maintenance guidelines.
Installation: Before installation, verify that the valve specifications match your system requirements, including voltage, pressure, and temperature ratings. Ensure that the valve is installed in the correct flow direction as indicated by the arrow on the valve body. Use appropriate fittings and avoid excessive force during installation to prevent damage.
Operation: Burkert solenoid valves operate by using an electromagnetic coil to control fluid flow. Ensure that the power supply matches the valve’s rated voltage and frequency. Avoid rapid cycling or frequent switching to prolong the valve’s lifespan. Monitor system parameters regularly to detect any deviations that may affect valve performance.
Maintenance: Regular inspection and maintenance are essential to maintain valve functionality. Periodically check the coil for signs of wear or overheating. Clean the valve internals to prevent clogging, especially when operating with fluids prone to contamination. Replace seals and other wear parts as needed, using genuine Burkert replacement components.
Troubleshooting: Common issues such as valve leakage, failure to actuate, or unusual noises can often be resolved by checking electrical connections, verifying coil resistance, and ensuring that the valve is free from debris. Refer to the product manual for detailed troubleshooting steps.
For detailed technical support, product manuals, spare parts, and service inquiries, please consult the official Burkert documentation and authorized service centers. Proper adherence to these guidelines will help maximize the efficiency and reliability of your Burkert solenoid valve installation.
