Product Description:
Bürkert 6281 Series Solenoid Valve
The Bürkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve specifically engineered for dependable shut-off, precise dosing, and filling applications involving neutral gaseous and liquid media, including compressed air and water. For optimal operation, the valve requires a minimum differential pressure to function correctly.
Designed to withstand vibrations, the valve features a centrally screwed coil system combined with a damped construction, which contributes to its quiet closing mechanism and extends its overall service life. To enhance energy efficiency during use, the valves can be equipped with coils featuring "Kick and Drop" (KD) electronics assembly, utilizing advanced double coil technology to reduce power consumption.
Constructed with a standard brass housing, the Bürkert 6281 complies with all European drinking water regulations, ensuring safety and reliability. Maintenance and commissioning are simplified thanks to an optional service-friendly manual override, allowing easy valve control when needed.
When paired with suitable cable plugs, such as Type 2518, these valves achieve an IP65 protection rating, safeguarding against dust and water ingress. The valve's flexible design allows installation in any orientation, although positioning the actuator upright is recommended for optimal performance.
Features:
Servo-Assisted Diaphragm Design
The valve features a servo-assisted diaphragm design that ensures dependable operation, making it ideal for applications involving shut-off, dosing, and filling. This design enhances reliability and precision in various industrial processes.
Normally Closed Configuration

Manual Override Capability
For ease of maintenance and commissioning, the valve includes a service-friendly manual override. This feature allows operators to manually control the valve when needed, facilitating troubleshooting and servicing.
Robust Brass Body Construction
Constructed from durable brass, the valve body offers excellent resistance to corrosion. This ensures a long service life even in demanding industrial environments, contributing to overall system longevity.
NBR Seal Material
The use of NBR seals guarantees reliable performance across a broad spectrum of neutral media. The seals operate effectively within a temperature range from -10°C to +80°C, adapting well to varying operational conditions.
Wide Range of Ports and Orifices
This valve supports a variety of port sizes, ranging from G1/4 up to G2, along with orifice sizes between 10 mm and 40 mm. This versatility allows it to accommodate diverse flow requirements across multiple applications.
Broad Pressure Operating Range
Designed for flexibility, the valve functions effectively under pressures from 0.2 bar to 16 bar. This makes it suitable for a wide array of industrial scenarios that demand different pressure levels.
Standard 8W Coils for Continuous Duty
The inclusion of standard 8W coils ensures a 100% continuous duty cycle, supporting reliable and long-lasting operation without overheating or performance degradation.
Multiple Voltage Options
To cater to global applications, the valve is available with several voltage options including DC24V, AC24V, and AC220V, all within a ±10% tolerance range. This facilitates easy integration into various electrical systems worldwide.
IP65 Protection Rating
The valve meets IP65 standards, making it dust-tight and protected against water jets when equipped with a suitable cable plug. This ensures durability and reliability even in harsh environments.
Vibration-Proof Coil System
Featuring a centrally screwed coil system, the valve maintains secure and stable operation even under demanding industrial conditions with significant vibration.
Quiet Closing with Damped Design
The damped design minimizes noise during valve closing, making it especially suitable for installation in noise-sensitive areas where quiet operation is essential.
Energy-Saving Technology
Incorporating the Kick-and-Drop (KD) double coil technology, the valve reduces power consumption during operation, promoting energy efficiency without compromising performance.
Drinking Water Compliance
The standard brass housing complies with all European regulations for drinking water, ensuring safe and hygienic use in potable water applications.
Explosion-Proof Variants
For hazardous environments, ATEX certified explosion-proof versions of the valve are available, providing enhanced safety where explosive atmospheres are present.
Flexible Installation Options
The valve supports flexible installation in any position, although it is preferably installed with the actuator in an upright orientation for optimal performance.
