Burkert Type 6281 FKM Sealed High Temp Solenoid Valve 00221992 00221993 00221994

Product Description:

The Burkert 6281 series represents a servo-assisted 2/2-way diaphragm solenoid valve engineered for dependable shut-off, dosing, and filling applications involving both neutral and aggressive gaseous and liquid media. This valve is constructed with a stainless steel body combined with an FKM (fluororubber) seal, providing outstanding corrosion resistance along with excellent performance at elevated temperatures.

To ensure full switching functionality, the valve requires a minimum differential pressure of 0.5 bar. Its design incorporates a vibration-resistant, centrally screwed coil system paired with damping elements, which results in quiet operation during closing and contributes to an extended service life of the valve.

The FKM diaphragm is specially designed to withstand exposure to hot air, chemical solutions, oils, and solvents. It supports media temperatures ranging from 0°C up to +90°C, and this range can be extended to +120°C when equipped with an epoxy-coated coil. The stainless steel body further enhances the valve's durability, making it well-suited for aggressive media and challenging environments.

To optimize power consumption during operation, the valve can be fitted with coils featuring "Kick and Drop" (KD) electronics assembly, which utilize double coil technology. Additionally, a manual override option is available to facilitate easy maintenance and commissioning processes.

When combined with a compatible cable plug adhering to DIN EN 175301-803 Form A standards, the valves achieve an IP65 protection rating. Installation flexibility is another advantage, as the valve can be mounted in any position; however, installation with the actuator in an upright position is preferred for optimal performance.

Features:

The product features a stainless steel body construction , which ensures excellent resistance to corrosion even when exposed to aggressive media and demanding environments. This robust construction enhances durability and longevity in various industrial applications.

Equipped with FKM (Fluororubber) seals , the device offers outstanding resistance to hot air, chemical solutions, oils, and solvents. It can handle media temperatures ranging from 0°C up to +90°C, and even up to +120°C when paired with an epoxy coil, making it suitable for a wide temperature spectrum.

The servo-assisted diaphragm design guarantees reliable operation for shut-off, dosing, and filling tasks involving both neutral and aggressive media. This design improves precision and functionality in fluid control processes.

Configured normally closed (Circuit function A - NC), the product ensures fail-safe operation for critical process control requirements, enhancing safety and reliability in automated systems.

It offers a wide range of port sizes and orifice options , from G1/4 to G1 1/2 ports and orifice diameters between 10 mm and 40 mm. This flexibility allows it to accommodate diverse flow rates and application needs comprehensively.

The unit operates efficiently across a broad pressure range, from 0.2 bar up to 16 bar, making it adaptable to various industrial pressure conditions.

Standard 8W coils provide a 100% continuous duty cycle , ensuring consistent and dependable long-term operation without the risk of coil overheating or failure.

Multiple voltage options are available, including DC24V, AC24V, and AC220V with a ±10% tolerance. This variety guarantees global compatibility and ease of integration into existing electrical systems.

With an IP65 rating , the device is dust-tight and protected against water jets when used in combination with an appropriate cable plug, making it suitable for harsh environments.

The vibration-proof coil system features a centrally screwed coil design that secures stable and safe operation even in demanding industrial settings with significant vibrations.

Its damped design facilitates quiet closing, reducing noise levels significantly, which is beneficial for use in noise-sensitive environments.

An energy-saving option utilizing Kick-and-Drop (KD) double coil technology minimizes power consumption during operation, contributing to cost-efficient and environmentally friendly performance.

The product also includes a manual override option to simplify maintenance and commissioning processes, allowing easy manual operation when necessary.

Installation is highly flexible, as the device can be installed in any position. However, it is preferably mounted with the actuator in an upright position to optimize performance.

For hazardous area applications, explosion-proof variants are available with ATEX certification, ensuring compliance with strict safety standards.
