Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve equipped with servo assistance, available in sizes up to DN 50. By utilizing a servo-assisted mechanism, this valve operates effectively with a minimal differential pressure, allowing it to manage large flow rates through a compact and energy-efficient coil system.
The valve body comes in multiple material options to suit diverse applications and meet international standards. These include standard brass compliant with European drinking water regulations, dezincification-resistant brass for enhanced durability, and stainless steel for handling various challenging media.
Incorporating integrated "Kick and Drop" energy-saving electronics combined with double coil technology, the Type 6281 guarantees reliable valve opening while significantly lowering power consumption during operation. Its design also features vibration resistance and quiet, damped closing for smooth performance.
Additionally, the valve offers an optional manual override, making it an excellent choice for industrial automation systems that require high efficiency, dependable operation, 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. Despite handling substantial flows, it maintains a compact design by utilizing a small solenoid for efficient operation.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) model incorporates an energy-efficient double coil mechanism. It begins with a high-power pulse to ensure positive valve opening and then switches to a low-power hold mode, significantly reducing energy consumption and keeping the system cool.
Robust & Quiet Design
Featuring a vibration-resistant coil secured by a centrally screwed system, this design guarantees a reliable electrical connection that withstands both vibration and shock. Additionally, an optimized pilot circuit combined with a damping mechanism promotes soft and quiet valve closing, reducing water hammer effects and minimizing operational noise.
Versatile Materials & Certifications
Available in various body materials including Brass and Stainless Steel, with standard brass versions meeting European drinking water standards. For hazardous environments, explosion-proof variants are certified according to ATEX and IECEx directives, ensuring safe usage in such areas.
Easy Maintenance & Commissioning
The valve is designed for user convenience, featuring an optional manual override that facilitates straightforward testing, maintenance, or emergency operation during power outages.
Long Service Life
A broad selection of diaphragm materials—such as NBR, EPDM, and FKM—ensures compatibility with various media and provides durable sealing, contributing to an extended product lifespan.
