Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve that utilizes a servo-assisted mechanism. Designed to accommodate sizes up to DN 50, this valve operates efficiently by requiring only a minimal differential pressure. This innovative approach allows it to control large flow rates while maintaining a compact form factor and an energy-efficient coil system.
Manufactured with versatility in mind, the valve body is available in several material options including standard brass, which complies with European drinking water regulations, dezincification-resistant brass, and stainless steel. These material choices ensure compatibility with a wide range of media and meet various international market standards.
One of the standout features of the Type 6281 is its integrated energy-saving "Kick and Drop" electronics combined with double coil technology. This setup guarantees reliable valve opening performance and significantly reduces power consumption during operation. Additionally, the valve’s vibration-resistant construction and damped, quiet closing mechanism contribute to its durability and user comfort.
With an optional manual override feature, the Bürkert Type 6281 valve is perfectly suited for industrial automation applications that demand high efficiency, exceptional reliability, and extended service life.
Features:
Servo-Assisted Operation
This system employs line pressure to actuate the diaphragm, enabling dependable control over large flow rates up to DN 50. It achieves this with a compact solenoid design, combining efficiency and reliability in a small form factor.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) variant features an innovative approach by utilizing a high-power pulse to initiate a positive opening, followed by a low-power hold phase. This method significantly reduces energy consumption and ensures the coil operates at a cooler temperature.
Robust and Quiet Design
Vibration-Resistant Coil
Equipped with a centrally screwed coil system, this design guarantees a secure electrical connection and offers high resistance against vibration and shock, enhancing durability in demanding environments.
Damped Closing
Through an optimized pilot circuit combined with a damping mechanism, the valve achieves soft and quiet closing actions. This minimizes water hammer effects and reduces operational noise, contributing to a smoother performance.
Versatile Materials and Certifications
The product is available in multiple body materials, including Brass and Stainless Steel. The standard brass variant complies with European drinking water standards, ensuring safety and quality.
Additionally, explosion-proof versions are offered with ATEX and IECEx certifications, making them suitable for use in hazardous areas where safety is paramount.
Easy Maintenance and Commissioning
An optional manual override feature is included, allowing for straightforward testing, maintenance, or emergency operation in the event of power failure. This enhances the system's usability and reliability.
Long Service Life
A diverse selection of diaphragm materials such as NBR, EPDM, and FKM is available. This variety ensures compatibility with different media and maintains long-term sealing integrity, extending the overall service life of the valve.
