Product Description:
The Burkert 5281 series represents a servo-assisted 2/2-way diaphragm solenoid valve engineered for dependable shut-off, dosing, and filling operations involving neutral gaseous and liquid substances. This valve is offered in two variants: normally closed (NC) and normally open (NO), catering to different system requirements.
Designed with an emphasis on durability and performance, the valve incorporates an anti-waterhammer feature and operates with low noise levels. To ensure full valve opening, a minimum differential pressure must be maintained during operation. The solenoid coils are encapsulated in high-quality epoxy resin, enhancing their longevity and resistance to environmental factors.
When paired with an appropriate cable plug, these valves achieve an IP65 protection rating, making them suitable for use in various industrial settings. The Burkert 5281 is compatible with neutral media, compressed air, and water applications. Additionally, explosion-proof versions compliant with ATEX standards are available, enabling safe use in hazardous environments.
Features:
The servo-assisted diaphragm design guarantees dependable performance, making it ideal for shut-off, dosing, and filling applications. This advanced design ensures consistent and accurate operation across various industrial needs.
Available in both normally closed (NC) and normally open (NO) configurations, the product offers circuit function A (NC) and circuit function B (NO). This flexibility supports fail-safe mechanisms as well as precise process control requirements.
Constructed with a robust brass body, the valve delivers excellent resistance to corrosion and ensures a long-lasting service life. The durable brass material is suitable for demanding environments and extends the overall reliability of the device.
To accommodate a wide range of media, multiple seal material options are available, including NBR (operating temperature from -10°C to +60°C), FKM, and EPDM. These diverse sealing materials provide broad compatibility with different fluids and chemicals.
The device supports a wide variety of port and orifice sizes, with port diameters ranging from G1/2 up to G2, and orifice sizes between 13 mm and 50 mm. This range ensures adaptability to various flow rates and system requirements.
Operating pressure spans from as low as 0.2 bar up to 16 bar, allowing suitability for numerous industrial processes. This extensive pressure range offers versatility for different working conditions.
Equipped with standard 8-watt coils, the valve can sustain a continuous 100% duty cycle, ensuring reliable long-term operation without overheating or performance degradation.
Multiple voltage options are provided, including DC 24V, AC 24V, and AC 220V, all with a ±10% tolerance. This variety supports global compatibility and ease of integration into existing electrical systems.
Featuring IP65 protection, the valve is dust-tight and safeguarded against water jets when paired with an appropriate cable plug. This makes it suitable for use in challenging environmental conditions.
For hazardous area applications, explosion-proof versions are available, certified according to ATEX standards (II 2G Ex e mb IIC T4 Gb). This certification guarantees safe operation in potentially explosive atmospheres.
The valve's anti-waterhammer design reduces noise generation, ensuring quiet and smooth performance. This feature is beneficial in noise-sensitive settings.
Installation is highly flexible, allowing the valve to be mounted in any orientation. However, optimal performance is achieved with the actuator positioned upright.
Finally, the valve is compatible with neutral media such as compressed air and water, making it suitable for a broad range of standard applications.
