FKM Fluorine Rubber Sealed 2 Position 2 Way NC Solenoid Valve Burkert 6281 Series G1 Port Anti‑corrosion Stainless Steel Housing 25mm Orifice Size 00221998 00221999 00222000

Product Description:

The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve designed to ensure reliable shut-off, dosing, and filling of both neutral and aggressive gaseous and liquid media. This valve combines precision engineering and robust materials to meet demanding industrial requirements.

Constructed with a stainless steel body and an FKM (fluororubber) seal, the valve delivers excellent corrosion resistance and outstanding performance under high-temperature conditions. For complete switching, a minimum differential pressure of 0.5 bar is necessary, ensuring efficient operation in various applications.

The coil system is vibration-resistant and centrally screwed, featuring a damped design that guarantees quiet closing actions and an extended service life. The FKM diaphragm is specially designed to resist hot air, chemical solutions, oils, and solvents, accommodating media temperatures ranging from 0°C up to +90°C, or even up to +120°C when paired with an epoxy coil.

With its durable stainless steel construction, the valve withstands challenging environments and aggressive media. To optimize energy efficiency, optional coils equipped with "Kick and Drop" (KD) electronics assembly, utilizing double coil technology, are available to reduce power consumption during operation.

Maintenance and commissioning are simplified thanks to an optional manual override feature. When combined with an appropriate cable plug conforming to DIN EN 175301-803 Form A standards, the valve achieves an IP65 protection class, ensuring resistance against dust and water ingress.

The Burkert 6281 valve offers versatile installation options, allowing placement in any position, although installation with the actuator upright is recommended for optimal performance.

Features:

The valve boasts a stainless steel body construction, delivering outstanding corrosion resistance suitable for handling aggressive media and operating in demanding environments. This robust material ensures durability and longevity even under harsh conditions.

Equipped with FKM (Fluororubber) seals, the valve resists exposure to hot air, various chemical solutions, oils, and solvents effectively. It supports a media temperature range from 0°C up to +90°C, and can handle temperatures as high as +120°C when paired with an epoxy coil.

The servo-assisted diaphragm design enhances operational reliability, making the valve ideal for shut-off, dosing, and filling applications involving both neutral and aggressive media. Its normally closed (NC) configuration, defined as circuit function A, ensures fail-safe operation critical for precise process control.

Offering a wide range of port and orifice sizes, the valve accommodates port dimensions from G1/4 to G1 1/2 and orifice diameters between 10 mm and 40 mm. This versatility allows it to meet diverse flow requirements efficiently. Additionally, it operates under a broad pressure spectrum, from 0.2 bar up to 16 bar.

Standard 8W coils support a 100% continuous duty cycle, guaranteeing dependable performance over extended periods. Multiple voltage options are available—including DC24V, AC24V, and AC220V—with a tolerance of ±10%, enabling compatibility with global electrical standards.

With an IP65 protection rating, the valve is dust-tight and safeguarded against water jets when used with a suitable cable plug. A vibration-proof coil system, secured by a central screw, assures stable operation in challenging industrial environments. Its damped design further supports quiet closing, minimizing noise in sensitive settings.

For enhanced energy efficiency, an optional Kick-and-Drop (KD) double coil technology is available, reducing power consumption during operation. Maintenance is simplified by a service-friendly manual override feature that facilitates easy commissioning and adjustments.

The valve offers flexible installation options and can be mounted in any orientation, although an upright actuator position is preferred for optimal performance. For hazardous area applications, explosion-proof variants certified to ATEX standards are also offered, ensuring safety and compliance.
