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, including compressed air and water. For optimal functionality, the valve requires a minimum differential pressure to operate effectively.
This valve is designed with a vibration-proof, centrally screwed coil system, ensuring durability and stability during use. Additionally, it features a damped mechanism that enables quiet closing, enhancing operational comfort. The solenoid coils within the valve are moulded with chemically resistant epoxy, which adds to their robustness and longevity.
To promote energy efficiency, the valve is available with electronically powered coils that reduce power consumption during operation. The standard valve housing is made from brass and complies with all European drinking water standards (KTW/W270), while a version with dezincification-resistant brass is offered for international markets.
For ease of maintenance and commissioning, the valve can be equipped with a service-friendly manual override. Furthermore, when combined with a suitable cable plug that meets the DIN EN 175301-803 Form A standard, the valve assembly achieves an IP65 protection rating. The Burkert 6281 series valve is designed for flexible installation and can be mounted in any position, though it is preferably installed with the actuator in an upright orientation.
Features:
The servo-assisted diaphragm design ensures dependable performance for a variety of processes including shut-off, dosing, and filling when dealing with neutral media. This design enhances the reliability and efficiency of valve operation.
Featuring a normally open configuration, the valve operates in a fail-open mode under Circuit function B (NO). This is ideal for applications where it is critical that the valve remains open when power is lost or de-energized.
Constructed with a durable brass body, the valve offers excellent resistance to corrosion, thereby guaranteeing a long service life even in challenging environments. The brass housing also complies with European standards for drinking water applications.
Equipped with NBR seal material, the valve operates reliably within a temperature range of -10°C to +80°C. This ensures the seal maintains integrity under different thermal conditions.
To accommodate a wide variety of flow requirements, the valve supports a broad range of port sizes from G1/4 up to G2, with orifice sizes varying between 10 mm and 50 mm.
Its operating pressure range spans from 0.2 bar to 16 bar, allowing it to be used effectively in many different pressure scenarios.
The valve is equipped with standard 8W coils that are designed to provide a continuous duty cycle at 100%, ensuring reliable operation over extended periods.
Multiple voltage options are available including DC24V, AC24V, and AC220V, each with a ±10% tolerance. This flexibility supports compatibility with global electrical systems.
An IP65 rating protects the valve against dust ingress and water jets, provided the use of an appropriate cable plug. This ensures robust protection in harsh outdoor or industrial environments.
The coil system is vibration-proof with a centrally screwed design, securing stable operation even in demanding industrial settings where vibration is common.
The damped design of the valve allows for quiet closing, making it suitable for noise-sensitive environments by minimizing operational sound.
An energy-saving option, utilizing Kick-and-Drop (KD) double coil technology, helps reduce power consumption throughout the valve’s operation, promoting efficiency.
For ease of maintenance and commissioning, a manual override option is available, allowing service personnel to operate the valve manually when necessary.
Additionally, explosion-proof variants of the valve are available, certified under ATEX standards, making them suitable for use in hazardous area applications.
The valve offers great installation flexibility as it can be mounted in any position, though it is recommended to keep the actuator in an upright orientation for optimal performance.
