Product Description:
The Bürkert Type 6281 is an advanced solenoid diaphragm valve designed for high performance and precision control. Available in sizes up to DN 50, this valve operates using a servo-assisted mechanism, which requires only a minimal differential pressure to function effectively. This innovative design allows it to manage large flow rates while maintaining a compact footprint and energy-efficient coil system.
To cater to various applications and meet international standards, the valve body is offered in multiple materials. These include standard brass compliant with European drinking water regulations, dezincification-resistant brass, and stainless steel. This versatility ensures compatibility with a broad range of media and environments worldwide.
The Type 6281 also incorporates integrated energy-saving electronics known as "Kick and Drop," featuring double coil technology. This setup guarantees dependable valve opening while substantially decreasing power consumption during operation. Additional features such as vibration-resistant construction, smooth and quiet closing, and an optional manual override enhance its suitability for demanding industrial automation contexts.
Overall, the Bürkert Type 6281 valve combines efficiency, reliability, and durability, making it an excellent choice for industrial applications that require long service life and consistent performance.
Features:
Servo-Assisted Operation
This system utilizes line pressure to actuate the diaphragm, enabling reliable control over large flow rates up to DN 50. Despite handling substantial flow, it maintains a compact design through the use of a small solenoid.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) variant employs a high-power pulse to achieve positive valve opening, followed by a low-power hold mode. This approach significantly reduces energy consumption while ensuring the coil stays cool during operation.
Robust & Quiet Design
The coil system is centrally screwed, which guarantees a secure electrical connection and provides excellent resistance to vibration and shocks. Additionally, the optimized pilot circuit combined with an effective damping mechanism allows for soft and quiet valve closing, minimizing water hammer effects and operational noise.
Versatile Materials & Certifications
Various body materials such as brass and stainless steel are available, with the standard brass version meeting European drinking water standards. For hazardous environments, explosion-proof models certified with ATEX and IECEx are offered.
Easy Maintenance & Commissioning
An optional manual override is provided, facilitating simple testing, maintenance, or emergency operation in case of power failure.
Long Service Life
The availability of a broad selection of diaphragm materials, including NBR, EPDM, and FKM, ensures compatibility with various media and maintains long-term sealing reliability.
