Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve designed with servo-assistance technology, available in sizes up to DN 50. This valve operates on a servo-assisted principle, which means it requires only a minimal differential pressure to function effectively. This feature allows it to manage large flow rates while maintaining a compact design and energy-efficient coil system.
The valve body is offered in several material options to satisfy diverse application requirements. These include standard brass, which complies with European drinking water standards, dezincification-resistant brass, and stainless steel. Such material versatility ensures the valve meets both the demands of different media and the stringent regulations of global markets.
One of the standout features of the Type 6281 is its integrated energy-saving "Kick and Drop" electronics combined with double coil technology. This innovative design guarantees reliable valve opening while significantly lowering the power consumption during operation. Additionally, its robustness is enhanced by a vibration-resistant construction and a damped, quiet closing mechanism.
For increased functionality, the valve also offers an optional manual override. These characteristics make the Bürkert Type 6281 an ideal choice in industrial automation settings where efficiency, dependability, and long service life are essential.
Features:
Servo-Assisted Operation
This system leverages line pressure to actuate the diaphragm, enabling reliable management of large flow rates up to DN 50. Despite the high flow capacity, it maintains a compact design by utilizing a small solenoid.
Energy-Saving Double Coil Technology
The “Kick and Drop” (KD) variant features an energy-efficient approach by delivering a powerful pulse to achieve a positive opening and then switching to a low-power hold mode. This method significantly reduces energy consumption while ensuring the coil remains cool during operation.
Robust & Quiet Design
The coil system is designed to withstand vibrations and shocks through a centrally screwed configuration, securing electrical connections firmly. Additionally, an optimized pilot circuit combined with a damping mechanism guarantees soft and quiet closing, which effectively minimizes water hammer and reduces operational noise.
Versatile Materials & Certifications
Available in multiple body materials such as brass and stainless steel, the standard brass variant meets European standards for drinking water safety. For hazardous environments, explosion-proof models are offered, certified with ATEX and IECEx for compliance.
Easy Maintenance & Commissioning
An optional manual override function allows for straightforward testing, maintenance, or emergency operation in case of power failure, ensuring reliable control and accessibility.
Long Service Life
A broad selection of diaphragm materials, including NBR, EPDM, and FKM, provides excellent compatibility with various media while maintaining long-term sealing performance and durability.
