Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve that features servo-assisted technology. It is available in sizes up to DN 50, making it suitable for a wide range of industrial applications. Utilizing a servo-assisted operating principle, this valve requires only a minimal differential pressure to function effectively, which allows it to manage large flow rates while maintaining a compact and energy-efficient coil system.
The valve body is offered in several durable materials to accommodate different media and comply with global market standards. Options include standard brass that meets European drinking water regulations, dezincification-resistant brass, and stainless steel. This variety ensures long-term reliability and adaptability in diverse environments.
Equipped with integrated energy-saving "Kick and Drop" electronics alongside double coil technology, the Type 6281 guarantees dependable valve opening while significantly lowering power consumption during operation. Its robust, vibration-resistant construction is complemented by a damped, quiet closing mechanism, enhancing the overall performance and lifespan of the valve.
Additionally, an optional manual override feature provides extra flexibility for maintenance and control. These attributes make the Bürkert Type 6281 an ideal choice for industrial automation systems that prioritize efficiency, reliability, and durability.
Features:
Servo-Assisted Operation
This system employs line pressure to actuate the diaphragm, enabling reliable regulation of large flow rates up to DN 50. Despite handling substantial flows, it maintains a compact design through the use of a small solenoid.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) model incorporates a high-power pulse for swift and positive valve opening, followed by a low-power holding current that reduces overall energy consumption. This results in cooler operation and enhanced efficiency.
Robust & Quiet Design
Vibration-Resistant Coil
Featuring a centrally screwed coil system, the valve ensures a secure and stable electrical connection. This design also provides excellent resistance to vibration and shock, promoting durability.
Damped Closing
An optimized pilot circuit combined with a damping mechanism delivers soft and quiet closing of the valve. This approach effectively minimizes water hammer effects and reduces operational noise.
Versatile Materials & Certifications
The valve body is available in multiple materials including Brass and Stainless Steel. The standard brass variant meets European drinking water standards, ensuring safe use in potable water applications.
For hazardous environments, explosion-proof versions are offered with ATEX and IECEx certifications, allowing secure operation in potentially explosive atmospheres.
Easy Maintenance & Commissioning
An optional manual override feature facilitates straightforward testing, maintenance, and emergency operation during power outages, enhancing operational flexibility.
Long Service Life
Available with a variety of diaphragm materials such as NBR, EPDM, and FKM, the valve ensures compatibility with different media and maintains long-lasting sealing performance.
