Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve engineered for reliable shut-off, dosing, and filling applications involving neutral gaseous and liquid media. To operate effectively, the valve requires a minimum differential pressure. Depending on the specific application needs, various diaphragm material combinations are available to optimize performance and durability.
Designed with a vibration-resistant, centrally screwed coil system and a damped configuration, this valve ensures quiet closing actions and a prolonged service life. To enhance energy efficiency during operation, coils featuring electronic power reduction technology are also offered, helping to reduce overall power consumption.
The standard version of the valve incorporates a brass housing that complies with all European drinking water standards (KTW/W270). For other markets, a dezincification-resistant brass option is available, along with a stainless steel model to suit more demanding environments. Additionally, the valve can be equipped with a service-friendly manual override to facilitate easy maintenance and commissioning procedures.
When combined with an appropriate cable plug that meets the DIN EN 175301-803 Form A standard, the valves achieve an IP65 protection class rating, ensuring robust protection against dust and water ingress. Installation flexibility is another advantage, as the valve can be mounted in any orientation, although positioning the actuator upright is recommended for optimal operation.
Features:
The servo-assisted diaphragm design ensures dependable performance in various applications such as shut-off, dosing, and filling processes. This innovative mechanism enhances the reliability and precision of fluid control in critical operations.
Featuring a normally closed (NC) circuit function, the valve provides fail-safe operation, making it ideal for stringent process control requirements. This safety feature helps maintain system integrity by defaulting to a closed position during power loss or malfunction.
The EPDM (ethylene-propylene-diene rubber) seal delivers excellent chemical resistance against water, dilute acids, alkalis, and a variety of other media. It supports media temperatures ranging from -30°C to +90°C, ensuring versatility across different industrial environments.
Constructed from durable brass, the valve body offers outstanding corrosion resistance and guarantees a long service life. This robust build enables the device to withstand demanding conditions while maintaining consistent operation.
Available in a range of port sizes from G1/4 to G2 and orifice sizes from 10 mm up to 50 mm, the valve can be customized to meet diverse flow requirements, accommodating various system designs and capacities.
The valve supports a wide pressure range, from 0.2 bar to 16 bar, allowing it to perform effectively under different pressure conditions. This flexibility makes it suitable for numerous industrial applications.
Equipped with standard 8W coils, the valve supports a 100% continuous duty cycle, ensuring reliable and long-term operation without overheating or performance degradation.
Multiple voltage options—including DC 24V, AC 24V, and AC 220V—with a tolerance of ±10% are available, providing compatibility for global electrical standards and simplifying integration into existing systems.
Protection rating IP65 is achieved when the valve is paired with an appropriate cable plug. This guarantees reliable performance even in harsh and challenging environmental conditions, safeguarding against dust and water ingress.
The vibration-proof, centrally screwed coil system secures stable operation in demanding industrial settings, minimizing risks of component loosening or failure due to mechanical vibrations.
Designed with a damping mechanism, the valve ensures quiet closing and minimizes noise generation, making it suitable for noise-sensitive environments and applications.
A service-friendly manual override option is provided for convenient maintenance and commissioning, allowing operators to manually actuate the valve when necessary without requiring power.
Compliant with European drinking water standards (KTW/W270), the standard brass housing is approved for use in drinking water applications, ensuring safety and hygiene.
For hazardous zones, ATEX-certified explosion-proof variants are available, expanding the valve’s usability to environments requiring stringent safety certifications.
The valve allows flexible installation in any orientation, although the actuator is ideally positioned upright to optimize performance and longevity.
Its high switching frequency capability makes it well-suited for demanding automation applications, providing rapid and reliable valve actuation for process efficiency.
