Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve that features servo assistance and is available in sizes up to DN 50. Utilizing a servo-assisted mechanism, this valve operates efficiently with a minimal differential pressure, allowing it to control large flow rates while maintaining a compact and energy-saving coil system.
The valve body options include standard brass that complies with European drinking water standards, dezincification-resistant brass, and stainless steel. These material choices ensure the valve meets the requirements of different media and adheres to various global market regulations.
Equipped with integrated energy-saving "Kick and Drop" electronics that incorporate double coil technology, the Type 6281 guarantees reliable valve opening. This system also significantly lowers power consumption during operation, enhancing overall energy efficiency.
Additional features such as a vibration-resistant design, damped quiet closing, and an optional manual override make the Type 6281 an excellent choice for industrial automation. It provides a combination of efficiency, dependability, and durability, making it well-suited for applications that demand long service life and consistent performance.
Features:
Servo-Assisted Operation
This system employs line pressure to actuate the diaphragm, enabling dependable control of large flow rates up to DN 50. Despite handling substantial volumes, the design incorporates a compact solenoid for efficient operation.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) model features a dual-coil mechanism that applies a powerful initial pulse to open valves positively. It then switches to a low-power holding mode, which significantly reduces energy consumption and keeps the device cool during use.
Robust & Quiet Design
The coil system is centrally screwed in place to guarantee a secure electrical connection. This setup boosts resistance against vibrations and shocks, contributing to the valve's durability and reliability.
Additionally, the closing process is finely tuned through an optimized pilot circuit paired with a damping mechanism. This combination ensures a soft, quiet shutoff that minimizes water hammer effects and reduces operational noise.
Versatile Materials & Certifications
Available in multiple body materials including brass and stainless steel, the standard brass model meets European drinking water standards. For hazardous environments, explosion-proof versions are offered with ATEX and IECEx certifications.
Easy Maintenance & Long Service Life
An optional manual override feature facilitates straightforward testing, maintenance, and emergency operation in case of power failure. Moreover, the availability of various diaphragm materials such as NBR, EPDM, and FKM ensures compatibility with different media and guarantees long-term sealing reliability.
