Burkert 6281 G3/8 Diaphragm Solenoid Valve Item 00322508 00322509 00322510 2/2‑Way Normally Closed With Manual Override 10mm Orifice NBR Elastomer Seal Brass Construction

Product Description:

The Bürkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve designed to provide reliable shut-off, precise dosing, and efficient filling for neutral gaseous and liquid media, including compressed air and water. Proper operation of the valve requires a minimum differential pressure to function effectively.

This valve features a vibration-resistant, centrally screwed coil system combined with a damped design, which ensures quiet closing actions and contributes to a long service life. To optimize energy efficiency during operation, the valves offer coils equipped with "Kick and Drop" (KD) electronics—a double coil technology that reduces power consumption.

Constructed with a standard brass housing, the Bürkert 6281 series meets all European standards for drinking water applications. Additionally, the valve can be fitted with a user-friendly manual override, facilitating straightforward maintenance and commissioning processes.

When paired with an appropriate cable plug—such as the Type 2518—the valves comply with the IP65 protection class, ensuring robust protection against dust and water ingress. Installation is flexible, allowing the valve to be mounted in any position, although it is recommended to position the actuator upright for optimal performance.

Features:

The servo-assisted diaphragm design ensures dependable performance in shut-off, dosing, and filling processes. This technology enhances the valve’s reliability for a variety of industrial applications.

Featuring a normally closed configuration with Circuit Function A (NC), the valve guarantees fail-safe operation to meet stringent process control requirements. This safety feature is crucial for maintaining system integrity.

A service-friendly manual override allows easy maintenance and commissioning, providing operators with convenient control whenever manual intervention is necessary.

Constructed with a robust brass body, the valve offers excellent corrosion resistance and extends the service life, making it suitable for demanding environments.

The use of NBR seal material ensures reliable performance across a broad temperature range from -10°C to +80°C. It is optimized for compatibility with various neutral media, enhancing operational versatility.

The valve supports a wide array of port sizes, ranging from G1/4 to G2, paired with orifice sizes between 10 mm and 40 mm. This variety allows for precise adaptation to different flow requirements.

With an operational pressure range extending from 0.2 bar to 16 bar, the valve caters to numerous industrial scenarios, ensuring flexibility and robust performance.

Standard 8W coils enable a 100% continuous duty cycle, assuring reliable and long-term operation without interruption.

Multiple voltage options are available, including DC 24V, AC 24V, and AC 220V, all featuring a ±10% tolerance. This diversity guarantees compatibility with global power standards.

Rated with IP65 protection, the valve is dust-tight and safeguarded against water jets when paired with a suitable cable plug, ensuring durability in harsh conditions.

The vibration-proof coil system, featuring a centrally screwed coil design, provides secure and stable operation even in demanding industrial environments.

A damped design contributes to quiet closing, minimizing noise levels and making the valve suitable for use in noise-sensitive settings.

An energy-saving option utilizing Kick-and-Drop (KD) double coil technology helps reduce power consumption during operation, promoting efficiency.

The standard brass housing complies with all European drinking water regulations, making this valve suitable for potable water applications.

For hazardous area applications, explosion-proof variants are available, certified under ATEX standards to ensure safety in potentially explosive atmospheres.

The valve allows flexible installation in any position, although installing with the actuator upright is preferred for optimal performance.
