Product Description:
The Bürkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve, specifically engineered for dependable shut-off, dosing, and filling applications involving neutral gaseous and liquid media like compressed air and water. The valve requires a minimum differential pressure to operate effectively.
Featuring a vibration-resistant and centrally screwed coil system along with a damped design, the valve guarantees quiet closing and an extended service life. To enhance energy efficiency during operation, the valve is available with coils that incorporate "Kick and Drop" (KD) electronics assembly, which utilizes double coil technology to reduce power consumption.
The valve's standard brass housing complies with all European drinking water standards, ensuring safety and reliability. For ease of maintenance and commissioning, the valve can be equipped with a user-friendly manual override. When combined with an appropriate cable plug, such as the Type 2518, the valve achieves an IP65 protection rating.
This solenoid valve can be installed in any orientation, though it is recommended to position the actuator upright for optimal performance.
