Product Description:
The Bürkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve, specifically engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media such as compressed air and water. Its operation requires a minimum differential pressure to function effectively.
Designed with durability in mind, the valve features a vibration-resistant, centrally screwed coil system along with a damped construction, which together ensure quiet closing actions and an extended service life. To enhance energy efficiency during operation, the valve is available with coils incorporating "Kick and Drop" (KD) electronics assembly, a double coil technology that helps reduce power consumption.
The valve’s standard brass housing complies with all European drinking water standards, ensuring safety and reliability. Additionally, it can be fitted with a service-friendly manual override, making maintenance and commissioning straightforward and convenient. When used with a compatible cable plug, such as the Type 2518, the valve achieves an IP65 protection rating.
Installation flexibility is another advantage of the Bürkert 6281 series, as the valve can be mounted in any orientation. However, positioning the actuator upright is recommended for optimal performance.
Features:
Servo-Assisted Diaphragm Valve Features
The valve features a servo-assisted diaphragm design that ensures dependable performance for a variety of applications including shut-off, dosing, and filling. This design enhances reliability across diverse industrial processes.
It comes with a normally closed (NC) configuration utilizing circuit function A, which guarantees fail-safe operation optimized for precise process control requirements. Additionally, a manual override option facilitates straightforward maintenance and commissioning tasks, making it user-friendly and serviceable.
Constructed with a durable brass body , the valve exhibits outstanding corrosion resistance and ensures long-term durability. The sealing is accomplished using NBR material , which reliably handles a wide variety of neutral media and operates effectively within temperatures ranging from -10°C to +80°C.
To accommodate varying flow demands, the valve offers a wide range of port sizes from G1/4 to G2 and orifice sizes between 10 mm and 40 mm. It is designed to operate efficiently under pressures starting at 0.2 bar and up to 16 bar, making it suitable for a broad spectrum of industrial uses.
The valve is equipped with standard 8W coils that support a 100% continuous duty cycle, ensuring dependable long-term operation. Multiple voltage options are available, including DC24V, AC24V, and AC220V with a ±10% tolerance, enabling compatibility with global electrical standards.
Protection features include an IP65 rating , guaranteeing that the device is dust-tight and protected against water jets when paired with an appropriate cable plug. Its vibration-proof coil system with a centrally screwed coil mechanism ensures secure and stable functioning even in challenging industrial environments.
The valve incorporates a damped design that allows for quiet closing, reducing noise levels in sensitive settings. An energy-saving option utilizing Kick-and-Drop (KD) double coil technology minimizes power consumption during operation, enhancing overall efficiency.
It meets stringent drinking water standards thanks to the standard brass housing, complying fully with European water quality requirements. For use in hazardous environments, explosion-proof variants certified by ATEX are also available.
Installation of this valve is highly flexible; it can be mounted in any orientation, although the actuator is preferably positioned upright to ensure optimal performance.
