Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve engineered for dependable shut-off, dosing, and filling applications involving both neutral and aggressive gaseous and liquid media. Constructed with a robust stainless steel body combined with an FKM (fluororubber) seal, this valve ensures exceptional resistance to corrosion and outstanding performance in high-temperature environments.
A minimum differential pressure of 0.5 bar is necessary to achieve complete switching of the valve. Its design includes a vibration-resistant, centrally screwed coil system alongside a damped mechanism, which work together to provide quiet closing operations and extend the valve’s service life. The FKM diaphragm specifically offers remarkable resistance against hot air, various chemical solutions, oils, and solvents, supporting media temperatures ranging from 0°C up to +90°C, and even reaching +120°C when using the epoxy coil variant.
Thanks to the stainless steel construction, the valve exhibits superior durability even when exposed to aggressive media and challenging operating conditions. To optimize energy efficiency, the valve is available with coils fitted with "Kick and Drop" (KD) electronic assemblies, which utilize double coil technology to reduce power consumption during use.
For ease of maintenance and commissioning, the valve can be equipped with a manual override feature. When used together with a compatible cable plug conforming to DIN EN 175301-803 Form A standards, the valve meets the IP65 protection class requirements. Installation is flexible as the valve can be positioned in any orientation, though it is recommended to install the actuator in an upright position for optimal performance.
Features:
The valve features a robust stainless steel body construction, which ensures excellent corrosion resistance when exposed to aggressive media and harsh operating environments. This durability makes it suitable for demanding applications where longevity and reliability are critical.
Equipped with FKM (Fluororubber) seal material, the valve provides superior resistance against hot air, various chemical solutions, oils, and solvents. It accommodates media temperatures ranging from 0°C up to +90°C, and can withstand temperatures as high as +120°C when paired with an epoxy coil.
The servo-assisted diaphragm design guarantees dependable performance for functions such as shut-off, dosing, and filling, handling both neutral and aggressive media efficiently. This technology enables precise and reliable control under diverse operating conditions.
Designed with a normally closed (NC) configuration, designated as circuit function A, the valve ensures fail-safe operation. This safety feature is essential for process control applications where preventing unintended flow is vital.
A broad selection of port and orifice sizes is available to meet various flow requirements. Port sizes range from G1/4 to G1 1/2, while orifice sizes span from 10 mm to 40 mm, allowing for tailored solutions suitable for a wide range of industrial processes.
The valve operates effectively over a wide pressure range, from as low as 0.2 bar up to 16 bar, allowing it to adapt to different system pressures and maintain consistent performance.
Standard 8W coils provide a 100% continuous duty cycle, ensuring reliable and long-term operation without risk of overheating. Multiple voltage options, including DC24V, AC24V, and AC220V with ±10% tolerance, offer compatibility for global applications.
With an IP65 rating, the valve is dust-tight and protected against water jets when used with a suitable cable plug, enhancing its durability in challenging environments. Furthermore, the vibration-proof coil system, secured by a centrally screwed design, maintains stable operation even in demanding industrial conditions.
The valve incorporates a damped design that enables quiet closing, making it ideal for use in noise-sensitive environments. Additionally, an energy-saving kick-and-drop (KD) double coil technology reduces power consumption during operation, contributing to efficient energy management.
For ease of maintenance and commissioning, a manual override option is available, allowing service personnel to operate the valve manually when needed. Installation is flexible, as the valve can be mounted in any position, though upright actuator installation is preferred for optimal performance.
Finally, explosion-proof variants with ATEX certification are offered for applications in hazardous areas, ensuring safety and compliance in environments where explosive gases or dust may be present.
