Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve specifically engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media, including compressed air and water. It is important to note that the valve requires a minimum differential pressure to operate correctly.
This valve is equipped with a vibration-resistant, centrally screwed coil system and incorporates a damped design to ensure quiet closing. The solenoid coils are encapsulated with chemically resistant epoxy to enhance durability. To optimize energy efficiency, versions with electronic power reduction are also available, significantly lowering power consumption during operation.
The standard model comes with a brass housing that meets all European drinking water standards (KTW/W270). For applications in other markets, options with dezincification-resistant brass are offered. Additionally, the valve can be fitted with a user-friendly manual override, allowing for straightforward maintenance and commissioning.
When paired with a compatible cable plug according to DIN EN 175301-803 Form A, the valve attains an IP65 protection rating, ensuring resistance against dust and water ingress. Installation flexibility is another advantage, as the valve can be mounted in any position, though positioning the actuator upright is recommended for optimal performance.
Features:
The servo-assisted diaphragm design ensures reliable performance in shut-off, dosing, and filling applications involving neutral media. This advanced design provides dependable operation under various conditions.
Equipped with a normally open configuration, the valve utilizes circuit function B (NO) to maintain an open state when de-energized. This feature is essential for applications that require the valve to stay open as a fail-safe measure.
Constructed with a durable brass body, the valve offers excellent resistance to corrosion and guarantees a long service life. This robust material choice ensures durability in demanding environments.
The sealing is made from NBR material, which delivers reliable performance across a temperature range from -10°C to +80°C. This makes the valve suitable for a variety of temperature conditions.
A wide range of port and orifice sizes is available, with port dimensions ranging from G1/4 to G2 and orifice sizes between 10 mm and 50 mm. This versatility allows the valve to meet diverse flow requirements with ease.
The valve operates effectively across a wide pressure range, from 0.2 bar up to 16 bar, accommodating various industrial pressure demands.
Standard 8W coils enable a 100% continuous duty cycle, ensuring reliable and long-term operation without interruptions or overheating concerns.
Multiple voltage options including DC 24V, AC 24V, and AC 220V with a tolerance of ±10% are available, offering global compatibility for various electrical standards.
The valve features IP65 protection, making it dust-tight and resistant to water jets when installed with an appropriate cable plug, thereby enhancing durability in harsh environments.
Its vibration-proof coil system, secured by a centrally screwed coil arrangement, provides stable operation even in demanding industrial settings where vibration is a concern.
The damped design ensures quiet closing, reducing noise levels and making the valve ideal for use in noise-sensitive environments.
An energy-saving option is available through the Kick-and-Drop (KD) double coil technology, which lowers power consumption during operation, enhancing efficiency.
For ease of maintenance and commissioning, a service-friendly manual override option is provided, allowing manual control when necessary.
The standard brass housing complies with all European drinking water requirements, making it suitable for applications involving potable water.
Explosion-proof variants are also offered, with ATEX certification for safe use in hazardous areas, ensuring compliance with stringent safety standards.
The valve supports flexible installation, capable of being mounted in any position, though it is preferably installed with the actuator oriented upright for optimal performance.
