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 innovative valve operates based on a servo-assisted principle, which requires only a minimal differential pressure to work effectively. This feature allows it to control large flow rates efficiently while utilizing a compact and energy-saving coil system.
The valve body comes in various materials to suit different media and comply with global standards. Options include standard brass that meets European drinking water regulations, dezincification-resistant brass for enhanced durability, and stainless steel for more demanding applications. This versatility ensures the Type 6281 can be used across a wide range of industries and environments.
Equipped with integrated energy-saving "Kick and Drop" electronic controls and advanced double coil technology, the valve guarantees reliable opening performance while significantly lowering power consumption during operation. Its design also incorporates vibration resistance and a damped, quiet closing mechanism to enhance longevity and reduce noise. Additionally, an optional manual override feature provides added control when needed.
Overall, the Bürkert Type 6281 stands out as an ideal choice for industrial automation systems that require efficiency, dependable operation, and extended service life.
Features:
Servo-Assisted Operation
This system leverages line pressure to actuate the diaphragm, enabling dependable control over large flow rates up to DN 50. All of this is achieved using a compact solenoid design, combining efficiency with space-saving benefits.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) variant employs a high-power pulse to achieve a positive opening, followed by a low-power hold mode. This approach significantly reduces energy consumption and keeps the device cool during operation.
Robust & Quiet Design
Vibration-Resistant Coil
The coil system is centrally screwed to secure the electrical connection firmly. This design provides excellent resistance against vibration and shocks, ensuring reliable performance even in demanding environments.
Damped Closing
An optimized pilot circuit combined with an efficient damping mechanism guarantees a soft and quiet closing process. This minimizes water hammer effects and reduces operational noise for smoother functionality.
Versatile Materials & Certifications
The product is available in several body materials, including Brass and Stainless Steel. The standard brass version meets the European drinking water standards, ensuring safety and compliance.
For hazardous areas, explosion-proof variants are offered, certified according to ATEX and IECEx standards, providing safe operation under strict regulatory conditions.
Easy Maintenance & Commissioning
An optional manual override feature simplifies testing, maintenance, and emergency operation, particularly during power failures, enhancing user convenience and system reliability.
Long Service Life
With a wide selection of diaphragm materials such as NBR, EPDM, and FKM, the device guarantees compatibility with various media. This versatility ensures durable sealing and long-term operational integrity.
