Big Diameter Thread Solenoid Valve Overhaul Assembly For Burkert 6281 G2 Port 2/2 NC EPDM Sealing Brass Housing 40.0 Flow Orifice Multi Voltage Coil 00221919 00221920 00221921

Product Description:

The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve engineered for dependable shut-off, dosing, and filling tasks involving neutral gaseous and liquid media. It is important to note that the valve requires a minimum differential pressure to operate effectively.

To cater to different applications, a variety of diaphragm material combinations are available. The valve features a vibration-resistant, centrally screwed coil system along with a damped design, which together ensure quiet closing and extend the service life of the product.

In order to minimize power consumption during operation, the valves can be equipped with coils that include electronic power reduction. The standard model comes with a brass housing that complies with all European drinking water standards (KTW/W270). For other markets, there is an option for dezincification-resistant brass, and a stainless steel version is also offered to complete the product range.

Maintenance and commissioning are made easier through the availability of a service-friendly manual override option. When used with a suitable cable plug that meets the DIN EN 175301-803 Form A standard, the valves achieve IP65 protection class. Furthermore, the valve can be installed in any orientation, although it is recommended to position the actuator in an upright manner.

Features:

The servo-assisted diaphragm design ensures reliable performance in various shut-off, dosing, and filling operations. This advanced mechanism guarantees precise control tailored for industrial processes.

Featuring a normally closed (NC) circuit function, the valve provides fail-safe operation that meets stringent process control requirements. This design helps maintain safety and reliability even in critical applications.

The EPDM (ethylene-propylene-diene rubber) seal delivers outstanding resistance against water, dilute acids, alkalis, and a broad range of other media. It can operate effectively within a temperature range spanning from -30°C to +90°C, making it versatile for many environments.

Constructed with a durable brass body, the valve offers exceptional corrosion resistance and ensures a long service life. This robust construction supports sustained operation in demanding industrial settings.

To accommodate diverse flow requirements, the product is available with port sizes ranging from G1/4 to G2 and orifice sizes from 10 mm up to 50 mm. This flexibility allows seamless integration into various system configurations.

The valve operates efficiently over a wide pressure range, from 0.2 bar to 16 bar, catering to numerous industrial pressures and applications.

Equipped with standard 8W coils, the valve supports a 100% continuous duty cycle, ensuring reliable and uninterrupted long-term performance.

Multiple voltage options are offered, including DC 24V, AC 24V, and AC 220V, each with a tolerance of ±10%, providing global compatibility and adaptability for various electrical systems.

When paired with an appropriate cable plug, the valve achieves IP65 protection, safeguarding its operation against dust and water ingress, which is vital for maintaining reliability in harsh environmental conditions.

The vibration-proof, centrally screwed coil system guarantees secure operation even in the most demanding industrial environments, minimizing the risk of malfunction caused by mechanical stress.

Thanks to its damped design, the valve operates quietly with smooth closing, making it suitable for environments where noise reduction is important.

Maintenance and commissioning are simplified by the service-friendly manual override, allowing easy manual control whenever necessary without dismantling the system.

The valve’s standard brass housing complies with European drinking water standards (KTW/W270), ensuring it is safe for use in potable water applications.

For use in hazardous areas, ATEX certified explosion-proof variants are available, providing compliance with safety regulations and enhancing operational safety.

Installation is highly flexible, allowing the valve to be mounted in any position, though it performs optimally when the actuator is oriented upright.

Designed to handle high switching frequencies, the valve is particularly well-suited for demanding automation tasks where rapid and repeated operation is required.
