Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve that features a servo-assisted mechanism and is available in sizes up to DN 50. This valve operates based on a servo-assisted principle, which means it requires only a minimal differential pressure to function effectively. This design allows it to handle large flow rates while maintaining a compact structure and an energy-efficient coil system.
The valve body comes in several material options to suit different applications and market requirements. These include standard brass that complies with European drinking water standards, dezincification-resistant brass, and stainless steel. Such a variety ensures the valve can be adapted to handle various media safely and reliably across global markets.
Equipped with integrated energy-saving "Kick and Drop" electronics and featuring double coil technology, the Type 6281 guarantees reliable valve opening actions while significantly reducing the power consumed during operation. Additionally, its vibration-resistant construction, smooth and quiet closing mechanism, and an optional manual override make it a versatile and durable solution.
Overall, the Bürkert Type 6281 is ideally suited for industrial automation applications where efficiency, reliability, and longevity are critical. Its advanced design elements and adaptable material options contribute to its outstanding performance in demanding environments.
Features:
Servo-Assisted Operation
This system employs line pressure to actuate the diaphragm, enabling dependable control over 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 an innovative energy-efficient approach. It generates a high-power
pulse to ensure positive valve opening, followed by a low-power holding current that minimizes energy usage and keeps
the coil cool during operation.
Robust and Quiet Design
Vibration-Resistant Coil
Featuring a centrally screwed coil system, the design guarantees a secure electrical connection while offering
excellent resistance against vibration and mechanical shocks, enhancing reliability in demanding environments.
Damped Closing
The pilot circuit has been optimized and includes a damping mechanism that results in soft and quiet valve closing.
This reduces water hammer effects and lowers noise levels during operation.
Versatile Materials and Certifications
The valve bodies are available in multiple materials, including brass and stainless steel. The standard brass version
meets European standards for drinking water safety. Additionally, explosion-proof variants are offered with ATEX and
IECEx certifications for use in hazardous locations.
Easy Maintenance and Commissioning
An optional manual override feature allows operators to conduct testing, maintenance, or emergency operations
conveniently during power outages, ensuring continued functionality.
Long Service Life
A variety of diaphragm materials, such as NBR, EPDM, and FKM, are available to ensure compatibility with different media.
This versatility contributes to a durable sealing performance over extended periods.
