Product Description:
The Burkert 5281 series is a servo-assisted 2/2-way diaphragm solenoid valve, engineered to ensure reliable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media. This valve is available in two configurations: normally closed (NC) and normally open (NO), providing flexibility for various application requirements.
Designed with an anti-waterhammer feature, the valve operates with minimal noise, enhancing the overall system performance. It requires a certain minimum differential pressure to fully open, guaranteeing optimal functionality under the specified conditions. The solenoid coils are encapsulated in high-quality epoxy resin, which contributes to their durability and long service life.
When paired with an appropriate cable plug, these valves achieve an IP65 protection rating, ensuring resistance against dust and water ingress. The valve is suitable for use with neutral media such as compressed air and water, making it versatile for many industrial environments. Furthermore, explosion-proof variants complying with ATEX standards are available, catering to demanding hazardous area applications.
Features:
Servo-Assisted Diaphragm Valve Features
The servo-assisted diaphragm design ensures dependable operation across various applications including shut-off, dosing, and filling. This technology enhances precision and reliability in fluid control processes.
Available in both Normally Closed (NC) and Normally Open (NO) configurations, the valve offers circuit functions A and B respectively. This versatility addresses fail-safe requirements and process control demands effectively.
Constructed with a robust brass body, the valve provides exceptional resistance to corrosion while ensuring a long operational lifespan. This durability makes it suitable for demanding industrial environments.
To accommodate a wide range of media, multiple seal material options are offered. These include NBR, suitable for temperatures ranging from -10°C to +60°C, as well as FKM and EPDM seals, providing broad compatibility with various substances.
The valve supports a broad selection of port and orifice sizes, ranging from G1/2 to G2 ports and orifice diameters between 13 mm and 50 mm. This flexibility allows it to meet diverse flow requirements efficiently.
Designed to operate within a wide pressure spectrum of 0.2 bar up to 16 bar, the valve is ideal for a variety of industrial applications, ensuring consistent performance under varying pressure conditions.
Equipped with standard 8-watt coils, the valve guarantees continuous duty cycle operation at 100%, supporting reliable and long-lasting use without interruption.
Multiple voltage options are available, including DC 24V, AC 24V, and AC 220V, each with a ±10% tolerance. This range ensures global compatibility across different electrical standards.
With an IP65 rating, the valve is dust-tight and protected against water jets when fitted with an appropriate cable plug, offering robust protection in challenging environments.
For hazardous areas, explosion-proof versions of the valve are ATEX certified under II 2G Ex e mb IIC T4 Gb standards, ensuring safe operation in potentially explosive atmospheres.
The innovative anti-waterhammer design minimizes noise during operation, providing quiet performance that is especially beneficial in noise-sensitive settings.
Installation flexibility is a key feature, as the valve can be mounted in any orientation. However, positioning the actuator upright is recommended for optimal function and longevity.
Finally, the valve is well-suited for use with neutral media, compressed air, and water, making it a versatile choice for many industrial fluid control applications.
