Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve engineered for dependable shut-off, dosing, and filling applications involving neutral gaseous and liquid media, such as compressed air and water. To ensure proper operation, the valve requires a minimum differential pressure.
This valve is designed with a vibration-proof, centrally screwed coil system that contributes to its durability and stability. Its damped construction provides quiet closing action, enhancing overall performance. Additionally, the solenoid coils are encapsulated with chemically resistant epoxy, ensuring long-lasting protection against harsh environmental conditions.
To optimize energy efficiency, coils equipped with electronic power reduction are available, which help minimize power consumption during operation. The standard version of the valve features a brass housing compliant with all European drinking water standards (KTW/W270). For applications outside European markets, a version with dezincification-resistant brass is offered.
Maintenance and commissioning are made easier with an optional service-friendly manual override. When combined with a compatible cable plug according to DIN EN 175301-803 Form A, the valves meet the IP65 protection rating, ensuring resistance against dust and water. The valve installation is flexible and can be performed in any orientation, though positioning the actuator upright is recommended for optimal functionality.
Features:
Servo-Assisted Diaphragm Valve Features
The valve incorporates a servo-assisted diaphragm design , ensuring dependable performance during shut-off, dosing, and filling operations with neutral media. This innovative design enhances operational reliability across various industrial applications.
Featuring a normally open configuration with circuit function B (NO), the valve remains open when de-energized. This fail-open characteristic is ideal for applications where maintaining an open state during power loss is critical for safety or process continuity.
Constructed with a durable brass body , the valve offers excellent resistance to corrosion, contributing to an extended service life. This robust material choice ensures longevity even in challenging working conditions.
The valve is equipped with NBR sealing material that performs reliably within a temperature range from -10°C to +80°C, making it suitable for a variety of operating environments.
It supports a wide range of ports and orifice sizes , with port sizes ranging from G1/4 up to G2, and orifice diameters between 10 mm and 50 mm. This flexibility allows the valve to meet diverse flow capacity requirements.
Operating within a pressure range from 0.2 bar to 16 bar, the valve is adaptable to various system pressures, enhancing its versatility across different processes.
Standard 8W coils deliver a 100% continuous duty cycle, ensuring steady and reliable long-term function. These coils are available in multiple voltage options, including DC24V, AC24V, and AC220V, with a tolerance of ±10% for broad global compatibility.
With an IP65 protection rating , the valve is dust-tight and guarded against water jets when used alongside an appropriate cable plug. This makes it suitable for harsh industrial environments.
The vibration-proof coil system , featuring a centrally screwed coil, guarantees secure and stable operation even under demanding conditions. Additionally, the valve employs a damped design to ensure quiet closing, which is beneficial in noise-sensitive settings.
An energy-saving option is available through Kick-and-Drop (KD) double coil technology, which reduces power consumption throughout operation. Maintenance and commissioning are simplified by a manual override option , allowing easy service intervention.
The valve meets drinking water approvals with its standard brass housing, complying with all relevant European regulations. For hazardous environments, explosion-proof variants certified to ATEX standards are also offered.
Installation is flexible, as the valve can be mounted in any position, though installation with the actuator oriented upright is preferred to optimize performance and longevity.
