Product Description:
The Burkert 6281 series features a servo-assisted 2/2-way diaphragm solenoid valve engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media. For optimal operation, the valve requires a minimum differential pressure.
There are multiple diaphragm material options available, allowing customization based on specific application needs. The valve's coil system is vibration-resistant and centrally screwed, complemented by a damped design that promotes quiet closing and extends the service life.
To enhance energy efficiency, the series offers coils equipped with electronic power reduction to lower power consumption during operation. The standard brass housing complies with all European drinking water regulations, including KTW and W270 standards.
For other markets, a dezincification-resistant brass variant is available, along with a stainless steel version to cover a wider range of requirements. Additionally, the valve can be fitted with a user-friendly manual override to facilitate easy maintenance and commissioning.
When paired with an appropriate cable plug conforming to DIN EN 175301-803 Form A, the valves achieve protection class IP65. Installation flexibility is another key feature, as the valve can be mounted in any position, although positioning the actuator upright is recommended for best results.
Features:
The servo-assisted diaphragm design ensures dependable operation across a variety of applications including shut-off, dosing, and filling processes. This design enhances control precision and reliability.
Featuring a normally closed (NC) circuit function, the system provides fail-safe operation essential for many process control requirements. This prevents unintended flow and ensures safety during system failures.
The seal is made from EPDM (ethylene-propylene-diene rubber), which offers exceptional resistance to water, dilute acids, alkalis, and various other media. It supports media temperatures ranging from -30°C up to +90°C, ensuring versatility in different environments.
Constructed with a durable brass body, the product boasts excellent corrosion resistance and a long service life. This makes it suitable for long-term industrial use even in challenging conditions.
It is available with port sizes ranging from G1/4 to G2 and orifice sizes between 10 mm and 50 mm, allowing users to select configurations that best fit their specific flow requirements.
The device supports a wide pressure range from 0.2 bar to 16 bar, accommodating diverse operational demands across sectors.
Standard 8W coils are used, providing a 100% continuous duty cycle. This guarantees reliable and consistent performance over extended periods.
Multiple voltage options are offered, including DC 24V, AC 24V, and AC 220V, each with a ±10% tolerance. This ensures compatibility with global electrical standards.
When paired with a suitable cable plug, the device achieves an IP65 rating. This level of protection ensures reliable operation even in harsh and dusty environments.
The coil system features a vibration-proof, centrally screwed design, which secures its operation in demanding industrial settings and reduces the risk of malfunction.
Thanks to a damped design, the valve closes quietly and operates with low noise, making it suitable for sensitive environments that require minimal acoustic disturbance.
For ease of maintenance and commissioning, a service-friendly manual override option is included, allowing manual operation when necessary.
The standard brass housing meets European drinking water standards (KTW/W270), granting approvals suitable for potable water applications.
Explosion-proof variants that are ATEX certified are available for use in hazardous areas, adding an extra layer of safety in potentially explosive atmospheres.
The device supports flexible installation orientations, though installation with the actuator in an upright position is recommended for optimal performance.
It is designed for high switching frequency, making it well-suited for demanding automation tasks where rapid and repeated operation is required.
