Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve that utilizes servo-assisted technology. Available in sizes up to DN 50, this valve operates on a servo-assisted principle which requires only a minimal differential pressure to function effectively. This design allows it to manage large flow rates while maintaining a compact structure and an energy-efficient coil system.
The valve body comes in several material options to suit various applications and comply with global standards. These options include standard brass, which meets European drinking water regulations, dezincification-resistant brass, and stainless steel. This variety ensures compatibility with different media and environments.
Equipped with integrated energy-saving "Kick and Drop" electronics utilizing double coil technology, the Type 6281 ensures consistent and reliable valve opening. This advanced technology also significantly reduces power consumption during operation, making it highly efficient.
Additional features of the Type 6281 include a vibration-resistant design and damped, quiet closing. An optional manual override is available for enhanced operational flexibility. All these characteristics make the Type 6281 an excellent choice for industrial automation applications that demand high efficiency, reliability, and a long service life.
Features:
Servo-Assisted Operation
This system leverages line pressure to actuate the diaphragm, enabling dependable control over large flow rates up to DN 50. Despite handling significant capacities, it maintains a compact solenoid design, ensuring efficiency without bulkiness.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) variant incorporates an innovative double coil mechanism. It utilizes a high-power pulse to achieve a positive valve opening, followed by a low-power hold mode that significantly reduces energy consumption. This also helps the coil to operate at a cooler temperature, enhancing overall durability.
Robust & Quiet Design
Vibration-Resistant Coil
Featuring a centrally screwed coil system, this design guarantees a secure electrical connection. It provides exceptional resistance to vibration and shock, making it suitable for demanding environments.
Damped Closing
The valve incorporates an optimized pilot circuit along with a damping mechanism to ensure soft and quiet closing actions. This reduces water hammer effects and minimizes operational noise for smoother performance.
Versatile Materials & Certifications
Available in multiple body materials including brass and stainless steel, the standard brass variants comply with European drinking water standards. Additionally, explosion-proof models are offered with ATEX and IECEx certifications, making them suitable for hazardous area applications.
Easy Maintenance & Commissioning
An optional manual override feature allows for straightforward testing and maintenance procedures. It also provides a reliable means of emergency operation in case of power failures.
Long Service Life
A broad selection of diaphragm materials such as NBR, EPDM, and FKM ensures compatibility with various media. This diversity helps maintain long-term sealing integrity and extends the overall service life of the system.

Support and Services:
Burkert solenoid valves are precision-engineered components designed for reliable and efficient fluid control in a wide range of industrial applications. To ensure optimal performance and longevity of your Burkert solenoid valve, it is important to follow the recommended installation, operation, and maintenance guidelines.
Installation:
Before installation, verify that the valve specifications match the system requirements, including pressure, temperature, and media compatibility. Install the valve in the correct orientation as indicated in the product manual. Ensure that all connections are secure and leak-free. Use appropriate sealing materials and avoid excessive tightening which can damage the valve body or seals.
Operation:
Operate the solenoid valve within the specified voltage and current ratings to prevent coil damage. Avoid rapid cycling that could reduce the valve’s lifespan. Monitor system pressure and flow to ensure the valve is functioning within its design parameters. In case of abnormal operation, shut down the system and inspect the valve.
Maintenance:
Regular maintenance is essential to maintain valve performance. Periodically inspect the valve for signs of wear, corrosion, or contamination. Clean or replace filters and strainers upstream of the valve to prevent debris from entering the valve mechanism. If the valve exhibits sticking or failure to actuate, check the coil and electrical connections, and replace any faulty components.
