Product Description
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve designed with servo-assisted technology, available in sizes up to DN 50. This valve operates based on a servo-assisted principle, requiring only a minimal differential pressure to function effectively. This enables the control of large flow volumes while utilizing a compact and energy-efficient coil system.
The valve body is offered in several material options to suit different applications and regulatory requirements. These include standard brass, which complies with European drinking water standards, dezincification-resistant brass, and stainless steel. This variety ensures compatibility with a wide range of media and global market demands.
Integrated into the valve is the advanced "Kick and Drop" electronics featuring double coil technology. This design guarantees reliable valve opening and substantially reduces power consumption during operation. Additionally, the valve's construction includes a vibration-resistant design and damped quiet closing, enhancing durability and operational smoothness.
For added convenience, the Bürkert Type 6281 also offers an optional manual override. Altogether, these features make it an excellent choice for industrial automation systems that require efficiency, dependability, and long-lasting performance.
Features:
Servo-Assisted Operation
This valve employs line pressure to actuate the diaphragm, enabling dependable control over large flow rates up to DN 50. Despite handling significant flow, it remains compact due to the use of a space-saving solenoid.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) version incorporates a double coil system that delivers a strong initial pulse to open the valve positively, followed by a low-power holding mode. This approach reduces energy consumption while maintaining a cool and efficient operation.
Robust and Quiet Design
The valve features a centrally fastened coil system that provides a secure electrical connection, offering excellent resistance against vibrations and shocks. Additionally, an optimized pilot circuit along with a damping mechanism enables soft and silent closing, significantly reducing water hammer and operational noise.
Versatile Materials and Certifications
Available in multiple body materials such as brass and stainless steel, the standard brass model meets European drinking water standards. For hazardous environments, explosion-proof versions are offered with ATEX and IECEx certifications.
Easy Maintenance and Commissioning
An optional manual override feature facilitates straightforward testing, maintenance, and emergency operation in case of power failure. This greatly simplifies the commissioning process and upkeep.
Long Service Life
The valve supports a wide selection of diaphragm materials, including NBR, EPDM, and FKM, to ensure compatibility with various media and maintain reliable sealing performance over an extended period.

Support and Services:
Burkert solenoid valves are precision-engineered components designed to control the flow of liquids and gases in a variety 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.
For installation, verify that the valve specifications match your application requirements, including pressure, temperature, and media compatibility. Ensure that the valve is installed in the correct orientation and that all connections are secure to prevent leaks. Use appropriate tools and avoid excessive force when mounting the valve.
During operation, monitor the valve for proper function and responsiveness. Solenoid valves rely on electrical signals to actuate; therefore, ensure that the power supply meets the voltage and current specifications outlined in the product datasheet. Avoid exposure to conditions outside the valve’s rated limits, such as extreme temperatures or corrosive environments, unless the valve is specifically designed for such conditions.
Regular maintenance is essential to maintain reliable operation. Periodically inspect the valve for signs of wear, contamination, or damage. Clean the valve components as recommended, and replace seals or coils if necessary. Use only genuine Burkert replacement parts to preserve valve integrity and performance.
If you encounter any issues with your Burkert solenoid valve, consult the troubleshooting section of the product manual for guidance. Common issues include coil burnout, valve sticking, or leakage, which can often be resolved through cleaning, adjustment, or part replacement.
For further technical support and detailed service information, refer to the official Burkert documentation or contact your authorized Burkert distributor. Professional assistance is available to help with complex installations, custom configurations, or advanced troubleshooting.
