Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve enhanced with servo-assist technology, available in sizes up to DN 50. Utilizing a servo-assisted mechanism, this valve operates efficiently by requiring only a minimal differential pressure. This design allows it to manage large flow rates while maintaining a compact form factor and energy-efficient coil system.
The valve body is offered in multiple materials to cater to diverse application needs and global standards. Options include standard brass compliant with European drinking water regulations, dezincification-resistant brass for enhanced durability, and stainless steel to handle a wide range of media. This versatility ensures the Type 6281 can be reliably used in various industrial environments.
Equipped with integrated energy-saving "Kick and Drop" electronics featuring double coil technology, the Type 6281 guarantees secure valve opening while significantly lowering power consumption during operation. Its robust design also incorporates vibration resistance and damped quiet closing to enhance longevity and performance. Additionally, an optional manual override is available for greater operational flexibility.
Overall, the Bürkert Type 6281 valve is an excellent choice for industrial automation applications that demand high efficiency, reliability, and an extended service life.
Features:
Servo-Assisted Operation
The valve employs servo-assisted operation by utilizing line pressure to actuate the diaphragm. This design enables dependable control over large flow rates, specifically up to DN 50, while maintaining a compact form factor thanks to the integrated solenoid.
Energy-Saving Double Coil Technology
Featuring the innovative "Kick and Drop" (KD) technology, this variant delivers a powerful high-current pulse for quick and positive valve opening. Subsequently, it switches to a low-power holding mode, effectively lowering energy consumption and ensuring cooler operation during extended use.
Robust and Quiet Design
The valve is built to withstand demanding environments and operate quietly. The vibration-resistant coil is centrally screwed, guaranteeing a secure electrical connection that resists vibration and shocks. Additionally, an optimized pilot circuit combined with a damping mechanism allows for smooth and silent closing, reducing water hammer and operational noise significantly.
Versatile Materials and Certifications
Available in multiple body materials, including brass and stainless steel, the valve meets various application needs. The standard brass model complies with European drinking water standards. For use in hazardous environments, explosion-proof variants certified by ATEX and IECEx are also offered.
Easy Maintenance and Commissioning
Maintenance and testing are simplified thanks to an optional manual override feature. This allows operators to manually control the valve during commissioning, routine maintenance, or in emergency situations such as power outages.
Long Service Life
To ensure durability and compatibility with various media, the valve is equipped with a wide selection of diaphragm materials including NBR, EPDM, and FKM. This variety supports long-term sealing integrity and reliable performance over an extended service life.
