Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve, engineered to provide reliable shut-off, precise dosing, and efficient filling of both neutral and aggressive gaseous and liquid media. Its design ensures dependable performance in a variety of applications requiring tight control and durability.
This valve boasts a robust stainless steel body combined with an FKM (fluororubber) seal, which delivers outstanding resistance to corrosion and enables operation under high-temperature conditions. For optimal function, a minimum differential pressure of 0.5 bar is necessary to achieve complete switching, ensuring consistent and accurate control.
The coil system features a vibration-resistant, centrally screwed design with damping, guaranteeing quiet closing and an extended service life. The FKM diaphragm is specifically chosen for its excellent resistance to hot air, chemical solutions, oils, and solvents. It supports a media temperature range from 0°C up to +90°C, which can be extended to +120°C when equipped with an epoxy coil.
Thanks to its stainless steel construction, the valve is highly durable and well-suited for handling aggressive media and operating in demanding environments. To enhance energy efficiency, coils with "Kick and Drop" (KD) electronic assemblies, utilizing double coil technology, are available to reduce power consumption during operation.
For ease of maintenance and commissioning, the valve can be fitted with a manual override. When used with a suitable cable plug compliant with DIN EN 175301-803 Form A, the valve assembly meets the IP65 protection class, ensuring reliable protection against dust and water. Installation flexibility is another advantage, as the valve can be mounted in any position, though it is recommended to install it with the actuator in an upright orientation for optimal performance.
