Big‑size Universal Solenoid Valve Burkert 5281 2/2 NC G2 Thread NBR Seal Brass

Product Description:

The Burkert 5281 series is a servo-assisted 2/2-way diaphragm solenoid valve, engineered to provide dependable shut-off, precise dosing, and efficient filling for neutral gaseous and liquid media. This valve is designed to ensure optimal performance in various fluid control applications.

Offering flexibility, the valve is available in both normally closed (NC) and normally open (NO) configurations. It incorporates an anti-waterhammer design that minimizes pressure surges, coupled with low-noise operation to maintain quiet environments during use. To achieve full valve opening, a minimum differential pressure is necessary.

The solenoid coils within the 5281 series are encapsulated in high-quality epoxy resin, enhancing durability and protection. When used with an appropriate cable plug, these valves conform to the IP65 protection rating, ensuring resistance against dust and water ingress.

Suitable for handling neutral media, compressed air, and water, the Burkert 5281 series is versatile across a range of industrial applications. For environments with hazardous conditions, explosion-proof variants compliant with ATEX standards are also offered, providing safety and reliability where it is most critical.

Features:

The servo-assisted diaphragm design ensures dependable performance across various applications including shut-off, dosing, and filling. Its advanced mechanism provides precise control, making it ideal for industrial processes that demand accuracy and reliability.

Available in both Normally Closed (NC) and Normally Open (NO) versions, the product offers flexibility to meet different process control and fail-safe requirements. Circuit function A represents the NC option, while circuit function B corresponds to the NO option, allowing users to select the configuration best suited to their operational needs.

Built with a robust brass body, this valve ensures excellent resistance to corrosion which contributes to a long service life. The sturdy construction makes it suitable for demanding environments, extending maintenance intervals and improving overall efficiency.

To accommodate a wide range of media, several seal materials are available, including NBR (suitable for temperatures from -10°C up to +60°C), FKM, and EPDM. This variety allows compatibility with diverse fluids and operating conditions.

The valve comes with port sizes ranging from G1/2 to G2 and orifice diameters between 13 mm and 50 mm. This extensive selection enables customization to match various flow rates and system requirements.

Designed to function efficiently within a pressure range of 0.2 bar to 16 bar, this valve can handle many industrial applications, providing flexibility and reliability under different pressure conditions.

Equipped with standard 8W coils, the valve supports a 100% continuous duty cycle. This feature guarantees stable and long-term operation without overheating or performance degradation.

Users can choose from various voltage options including DC24V, AC24V, and AC220V, each with a tolerance of ±10%. This ensures global compatibility and ease of integration into existing electrical systems.

The valve is rated IP65, meaning it is fully dust-tight and protected against water jets when paired with an appropriate cable plug. This protection makes it suitable for harsh environmental conditions.

For hazardous areas, explosion-proof versions are available that hold ATEX certification (II 2G Ex e mb IIC T4 Gb). These models ensure safe operation in potentially explosive atmospheres.

Featuring an anti-waterhammer design, the valve operates with minimal noise, making it ideal for sensitive environments where quiet performance is essential.

Installation is versatile, allowing the valve to be mounted in any position. However, for optimal performance, it is recommended to install the actuator in an upright position.

The valve is compatible with neutral media such as compressed air and water, broadening its range of applications across different industrial sectors.
