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.
