Product Description:
The Bürkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve specifically engineered for dependable shut-off, precise dosing, and effective filling of neutral gaseous and liquid media, including compressed air and water. For optimal performance, the valve requires a minimum differential pressure.
Its design features a vibration-resistant coil system that is centrally screwed, combined with a damped mechanism to ensure quiet closing operations and an extended service life. To enhance energy efficiency, the valve offers coils equipped with "Kick and Drop" (KD) electronics assembly, utilizing double coil technology to reduce power consumption during use.
The valve's standard brass housing complies with all European drinking water standards, ensuring safety and reliability. Additionally, it can be fitted with a user-friendly manual override, facilitating easy maintenance and commissioning tasks.
When paired with an appropriate cable plug, such as Type 2518, the Bürkert 6281 valves achieve an IP65 protection rating, making them suitable for various operating environments. The valve is versatile in installation and can be mounted in any position, though it is recommended to position the actuator upright for best results.
