Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve that features servo-assisted operation and is available in sizes up to DN 50. Utilizing a servo-assisted principle, this valve requires only a minimal differential pressure to operate effectively, allowing it to manage large flow volumes while maintaining a compact and energy-efficient coil system.
The valve body comes in a variety of materials to suit different applications and comply with international standards. Options include standard brass, which meets European drinking water regulations, dezincification-resistant brass for enhanced durability, and stainless steel for demanding media and global market requirements.
Equipped with integrated energy-saving "Kick and Drop" electronics and double coil technology, the Type 6281 guarantees reliable valve opening, while substantially reducing power consumption during operation. Its robust, vibration-resistant construction, quiet damped closing mechanism, and available manual override make it an excellent choice for industrial automation systems that prioritize efficiency, dependability, and longevity.
Features:
Servo-Assisted Operation
This system employs line pressure to actuate the diaphragm, enabling reliable control over large flow rates up to DN 50. It achieves this functionality while maintaining a compact solenoid design.
Energy-Saving Double Coil Technology
The innovative "Kick and Drop" (KD) variant features a high-power pulse that ensures positive valve opening, followed by a low-power hold mode. This approach significantly reduces energy consumption and keeps the operation cool.
Robust & Quiet Design
Vibration-Resistant Coil
The coil system is centrally screwed to provide a secure electrical connection, offering exceptional resistance against vibration and shock.
Damped Closing
Incorporating an optimized pilot circuit along with a damping mechanism, the valve closes softly and quietly, effectively minimizing water hammer effects and operational noise.
Versatile Materials & Certifications
The valve body is available in multiple materials, including Brass and Stainless Steel. The standard brass version complies with European drinking water standards.
Additionally, explosion-proof variants are offered, certified with ATEX / IECEx, making them suitable for use in hazardous environments.
Easy Maintenance & Commissioning
An optional manual override feature simplifies testing, maintenance, and emergency operation, especially useful during power failures.
Long Service Life
A comprehensive selection of diaphragm materials such as NBR, EPDM, and FKM guarantees compatibility with various media and ensures durable sealing performance over time.

Support and Services:
Burkert solenoid valves are precision-engineered components designed for reliable fluid control in a wide range of industrial applications. For optimal performance and longevity of your Burkert solenoid valve, it is important to follow the recommended installation, operation, and maintenance guidelines provided by Burkert.
Installation: Ensure that the valve is installed in the correct orientation and that the electrical connections comply with the specified voltage and current ratings. Use appropriate fittings and tools to avoid damaging the valve body or seals. Verify that the media is compatible with the valve materials to prevent corrosion or degradation.
Operation: Operate the valve within the specified pressure, temperature, and voltage limits. Avoid rapid cycling to minimize wear and extend the service life. Monitor the valve for any unusual noises, leaks, or fluctuations in performance, which could indicate potential issues.
Maintenance: Regular inspection and cleaning of the valve and its components are essential. Replace worn or damaged seals and diaphragms promptly to prevent leaks. If the valve is exposed to harsh environments or aggressive media, more frequent maintenance may be necessary. Always use genuine Burkert replacement parts to ensure compatibility and reliability.
