Product Description:
The Burkert 5281 series is a servo-assisted 2/2-way diaphragm solenoid valve engineered to provide reliable shut-off, precise dosing, and efficient filling for neutral gaseous and liquid media. This valve is available in two configurations: normally closed (NC) and normally open (NO), offering flexibility to suit various application requirements.
Designed with an anti-waterhammer feature, the valve operates with low noise, enhancing performance and longevity. It requires a minimum differential pressure to achieve full opening, ensuring optimal functionality. The solenoid coils are encapsulated in high-quality epoxy resin, which ensures durability and protection against environmental factors.
When paired with an appropriate cable plug, these valves comply with the IP65 protection rating, providing reliable resistance against dust and water ingress. The valve is well-suited for handling neutral media, compressed air, and water, making it versatile across different industrial applications.
For use in hazardous environments, explosion-proof versions compliant with ATEX standards are also available. This makes the Burkert 5281 series an excellent choice for safety-critical installations where both performance and compliance are essential.
Features:
Servo-Assisted Diaphragm Valve Features
The servo-assisted diaphragm design guarantees dependable performance, making it ideal for applications such as shut-off, dosing, and filling. This advanced mechanism ensures precise and reliable operation in various industrial settings.
To accommodate diverse process control requirements, the valve is available in both normally closed (circuit function A) and normally open (circuit function B) versions. These options provide flexibility for fail-safe operation and tailored process management.
Constructed with a rugged brass body, the valve offers excellent resistance to corrosion and ensures a long service life even under demanding conditions. This durable material choice contributes significantly to the product's reliability and longevity.
Multiple seal material options are offered to enhance media compatibility. Users can select from NBR, which is suitable for temperatures ranging from -10°C to +60°C, as well as FKM and EPDM seals, allowing for broad adaptability to different fluids.
The valve supports a wide range of port sizes, from G1/2 up to G2, and orifice diameters ranging between 13 mm and 50 mm. This variety enables matching the valve precisely to diverse flow rate requirements encountered in industrial processes.
Operating efficiently over a broad pressure spectrum from 0.2 bar to 16 bar, the valve meets the demands of numerous industrial applications. This wide pressure range enhances its versatility across different operational environments.
Equipped with standard 8W coils, the valve ensures a 100% continuous duty cycle, providing reliable and sustained long-term operation without overheating or performance degradation.
It is available with multiple voltage options including DC24V, AC24V, and AC220V, each with a tolerance of ±10%. This makes the valve compatible with global electrical standards and simplifies integration into existing systems.
The valve features an IP65 rating, making it dust-tight and protected against water jets when paired with an appropriate cable plug. This level of ingress protection ensures reliable functioning in harsh environments.
For use in hazardous areas, explosion-proof versions are available, certified under ATEX (II 2G Ex e mb IIC T4 Gb). This certification provides safety assurance in environments with explosive atmospheres.
Designed with an anti-waterhammer feature, the valve operates with low noise and minimizes pressure surges, resulting in quiet performance ideal for noise-sensitive applications.
Installation is highly flexible, allowing the valve to be mounted in any position. However, positioning the actuator upright is recommended to achieve optimal performance and durability.
The valve is suitable for neutral media, including compressed air and water, ensuring broad applicability across various fluid handling tasks.
