Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve, engineered to provide reliable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media. For optimal operation, the valve requires a minimum differential pressure to function effectively. Depending on the specific application needs, a variety of diaphragm material combinations are available to ensure compatibility and performance.
Designed with durability in mind, the valve features a vibration-resistant, centrally screwed coil system paired with a damped design that guarantees quiet closing and an extended service life. To enhance energy efficiency during operation, coils equipped with electronic power reduction are offered, reducing overall power consumption.
The standard version of the valve is housed in brass, fully compliant with all European drinking water standards (KTW/W270). For markets requiring additional resistance, a dezincification-resistant brass option is available. Additionally, a stainless steel variant is offered to complete the product range. For ease of maintenance and commissioning, the valve can be fitted with a service-friendly manual override.
When combined with a compatible cable plug following the DIN EN 175301-803 Form A standard, these valves meet the protection class IP65 requirements. Installation flexibility allows the valve to be positioned in any orientation, although the preferred installation is with the actuator facing upwards to ensure optimal performance.
Features:
The servo-assisted diaphragm design ensures dependable performance for a variety of applications including shut-off, dosing, and filling processes. This innovative mechanism enhances operational reliability across different industrial scenarios.
Featuring a normally closed (NC) circuit function, the system guarantees fail-safe operation crucial for precise process control. This safety feature helps maintain system integrity during unexpected interruptions.
The seal is made from EPDM (ethylene-propylene-diene rubber), known for its outstanding resistance to water, dilute acids, alkalis, and various other media. It supports media temperatures ranging from -30°C up to +90°C, making it versatile for many environments.
The valve body is constructed from durable brass, offering excellent corrosion resistance and a long service lifespan. This robust construction ensures reliability even in challenging conditions.
To accommodate diverse flow requirements, the product is available in various port sizes ranging from G1/4 to G2, and orifice sizes between 10 mm and 50 mm. This versatility allows it to fit a broad spectrum of system designs.
The valve supports a wide pressure range spanning from 0.2 bar to 16 bar, allowing it to be used effectively in many different pressure conditions.
Equipped with standard 8W coils, the unit supports a 100% continuous duty cycle, ensuring consistent and long-term reliable operation without overheating risks.
Multiple voltage options are offered, including DC24V, AC24V, and AC220V, each with a ±10% tolerance, making the device compatible with electrical standards worldwide.
When paired with an appropriate cable plug, the valve achieves IP65 protection, ensuring dependable performance even in harsh or dusty environments.
The vibration-proof, centrally screwed coil system enhances stability and secure operation, especially in demanding industrial settings that experience constant vibration.
The damped design contributes to quiet closing actions, reducing noise levels significantly, which is particularly beneficial in noise-sensitive environments.
For ease of maintenance and commissioning, a service-friendly manual override feature is included, allowing manual operation when necessary.
The standard brass housing complies with European drinking water standards (KTW/W270), making it suitable for potable water applications.
For use in hazardous areas, ATEX-certified explosion-proof variants are available, ensuring safety and compliance with rigorous industrial regulations.
The valve offers flexible installation options in any orientation, although installing it with the actuator in an upright position is recommended for optimal performance.
With a high switching frequency capability, this solution meets the demands of modern automation applications, ensuring efficient and rapid operation.
