Product Description:
The Bürkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve specifically engineered to provide reliable shut-off, precise dosing, and efficient filling for neutral gaseous and liquid media, including compressed air and water. This valve requires a minimum differential pressure to ensure proper functionality.
Featuring a vibration-resistant and centrally screwed coil system, the valve boasts a damped design that guarantees quiet closing and an extended service life. To enhance energy efficiency during operation, the series offers coils equipped with "Kick and Drop" (KD) electronics assembly, which utilizes double coil technology to significantly reduce power consumption.
Constructed with a standard brass housing, the Bürkert 6281 valve complies with all European drinking water regulations. It can also be fitted with a service-friendly manual override, making maintenance and commissioning straightforward and convenient. When paired with an appropriate cable plug, such as the Type 2518, the valve achieves an IP65 protection rating.
Installation flexibility is another advantage of this valve, as it can be mounted in any position. However, it is recommended to install the valve with the actuator in an upright position to ensure optimal performance.
