Product Description:
The Burkert 5281 series represents 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 designed to meet the demands of various applications requiring dependable control of fluid flow.
Offered in both normally closed (NC) and normally open (NO) configurations, the valve incorporates an innovative anti-waterhammer feature that ensures smooth operation while minimizing noise. It requires a minimum differential pressure to achieve full opening, thereby enhancing its operational stability and effectiveness.
The solenoid coils within the valve are encapsulated using premium epoxy resin, which contributes to durability and long-lasting performance. When paired with an appropriate cable plug, the valve complies with the IP65 protection class, guaranteeing resistance against dust and water ingress.
Designed to handle neutral media such as compressed air and water, the Burkert 5281 series is also available in explosion-proof versions that conform to ATEX standards. These specialized versions provide safe and reliable operation in hazardous environments, making the valve versatile for a wide range of industrial applications.
Features:
The servo-assisted diaphragm design ensures reliable performance for a variety of applications including shut-off, dosing, and filling operations. This advanced design enhances control precision and operational dependability.
Offering both Normally Closed (NC) and Normally Open (NO) versions, the device supports Circuit Function A and Circuit Function B respectively. This flexibility allows it to meet different fail-safe requirements and process control scenarios effectively.
Constructed with a robust brass body, the product delivers excellent corrosion resistance and is built for long service life. This durable material choice makes it suitable for demanding industrial environments.
To accommodate a broad range of media, multiple seal material options are available. These include NBR, suitable for temperatures from -10°C to +60°C, as well as FKM and EPDM seals, ensuring compatibility with various substances.
The product offers a wide selection of port and orifice sizes, with ports ranging from G1/2 to G2 and orifice diameters between 13 mm and 50 mm. This range enables customization to match diverse flow requirements precisely.
Designed to operate over a wide pressure range, it functions effectively from as low as 0.2 bar up to 16 bar, making it adaptable for multiple industrial applications.
Equipped with standard 8W coils, the device supports a 100% continuous duty cycle, ensuring reliable performance over extended periods without overheating.
Multiple voltage options are provided, including DC24V, AC24V, and AC220V, each with a ±10% tolerance. This variety promotes global compatibility and simplifies integration into existing systems.
The unit carries an IP65 protection rating, making it dust-tight and resistant to water jets when used with an appropriate cable plug. This level of protection is ideal for harsh operating environments.
For use in hazardous areas, explosion-proof versions are available. These models are ATEX certified (II 2G Ex e mb IIC T4 Gb), ensuring safety compliance in potentially explosive atmospheres.
The device features an anti-waterhammer design that minimizes noise, providing quiet operation suitable for environments sensitive to sound disturbances.
Installation is highly flexible, allowing the device to be mounted in any position. However, it is recommended to install it with the actuator in an upright position to optimize performance.
Finally, the valve is suitable for neutral media such as compressed air and water, broadening its application range across various industrial processes.
