Product Description:
The Bürkert Type 6281 represents a high-performance solenoid diaphragm valve that is servo-assisted, available in sizes up to DN 50. Its operation relies on a servo-assisted mechanism, which requires only a minimal differential pressure to function effectively. This design allows the valve to handle large flow rates while maintaining a compact size and energy-efficient coil system.
The valve body is offered in a variety of materials to suit different applications and market requirements. These include standard brass compliant with European drinking water standards, dezincification-resistant brass, and stainless steel. This variety ensures compatibility with a wide range of media and meets international standards across global markets.
One of the key features of the Type 6281 is its integrated energy-saving "Kick and Drop" electronics, which utilize double coil technology. This enables reliable valve opening while significantly reducing the power consumption during operation. In addition, the valve’s vibration-resistant construction and damped quiet closing ensure smooth and dependable performance.
With an optional manual override available, the Type 6281 is perfectly suited for industrial automation environments where efficiency, reliability, and durability are essential. Its thoughtful design makes it an ideal choice for applications requiring long service life combined with energy efficiency.
Features:
Servo-Assisted Operation
This system employs line pressure to activate the diaphragm, enabling dependable control over large flow rates reaching up to DN 50. Despite handling substantial flows, it maintains a compact design thanks to the use of a small solenoid.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) model features a dual-mode coil operation: it initiates movement with a powerful pulse for positive valve opening, then switches to a low-power state to hold the position. This approach significantly reduces energy consumption and ensures the coil operates at a cooler temperature.
Robust & Quiet Design
The coil system is centrally screwed in place, which guarantees a secure electrical connection and provides high resistance against vibrations and shocks. Additionally, the valve benefits from an optimized pilot circuit paired with a damping mechanism that produces smooth and silent closing actions, thereby minimizing water hammer effects and reducing operational noise.
Versatile Materials & Certifications
Available in multiple body materials including Brass and Stainless Steel, the standard brass option complies with European regulations for drinking water safety. For use in hazardous environments, explosion-proof variants with ATEX and IECEx certifications are offered.
Easy Maintenance & Commissioning
An optional manual override feature allows for straightforward testing, maintenance, or emergency operation in the event of power failure, simplifying both commissioning and upkeep processes.
Long Service Life
A diverse selection of diaphragm materials such as NBR, EPDM, and FKM ensures compatibility with a wide range of media and guarantees long-term sealing performance, contributing to the valve's extended service life.
