Product Description:

The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve, specifically engineered to provide reliable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media. The operation of this valve requires a minimum differential pressure to ensure optimal functionality.

To accommodate various applications, the valve is available with multiple diaphragm material options. Its robust construction includes a vibration-resistant, centrally screwed coil system coupled with a damped design, which guarantees quiet closing actions and extends the valve’s service life.

In order to minimize power consumption during use, coils featuring electronic power reduction are offered. The standard brass housing complies with all European drinking water standards (KTW/W270), while a dezincification-resistant brass variant is available to meet requirements in other markets. Additionally, a stainless steel version completes the range of housing options.

For ease of maintenance and commissioning, the valve can be equipped with a service-friendly manual override. When paired with a compatible cable plug conforming to DIN EN 175301-803 Form A, the valve achieves protection class IP65. Installation flexibility is provided, as the valve can be mounted in any position, though it is recommended to position the actuator upright.

Features:

The servo-assisted diaphragm design ensures reliable and efficient operation, making it ideal for shut-off, dosing, and filling applications. This innovative mechanism enhances control and precision in various industrial processes.

Featuring a normally closed (NC) circuit function, the valve guarantees fail-safe operation to meet stringent process control requirements. This safety feature helps prevent unintended flow during power loss or system failure.

The valve is equipped with an EPDM (ethylene-propylene-diene rubber) seal that offers excellent resistance to water, dilute acids, alkalis, and a variety of other media. It can operate within a temperature range from -30°C to +90°C, making it suitable for diverse environments.

Constructed from durable brass, the valve body provides outstanding corrosion resistance and ensures a long service life even under demanding conditions. This robust construction enhances overall reliability.

To accommodate different flow requirements, the valve is available in multiple port sizes ranging from G1/4 to G2, with orifice sizes between 10 mm and 50 mm. This flexibility allows for easy integration into various systems.

The product supports a wide pressure range from 0.2 bar up to 16 bar, allowing it to function effectively across numerous industrial applications.

Equipped with standard 8W coils, the valve supports a 100% continuous duty cycle, ensuring reliable performance and long-term operation without overheating.

Voltage options include DC 24V, AC 24V, and AC 220V, all with a ±10% tolerance, providing compatibility for global usage and simplifying integration with existing electrical systems.

Achieving an IP65 protection rating when used with an appropriate cable plug, the valve offers reliable operation in harsh and dusty environments, safeguarding against ingress of water and particles.

The vibration-proof, centrally screwed coil system ensures secure and stable functioning in demanding industrial conditions, reducing the risk of coil displacement or damage.

Its damped design enables quiet closing and low noise levels, making it suitable for sensitive environments where noise reduction is crucial.

A service-friendly manual override is available, facilitating easy maintenance and commissioning without the need for special tools or disassembly.

The standard brass housing complies with European drinking water standards (KTW/W270), making this valve suitable for potable water applications.

For hazardous area operations, ATEX-certified explosion-proof variants are available, ensuring safe use in environments prone to explosive gases or dust.

The valve can be installed in any position, although it performs best when the actuator is upright, enabling optimal functionality and longevity.

Capable of high switching frequencies, this valve meets the demands of advanced automation applications requiring rapid and frequent operation.
