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 designed to meet demanding application requirements while ensuring optimal performance.
Available in both normally closed (NC) and normally open (NO) configurations, the valve is equipped with an anti-waterhammer feature and a low-noise design. It requires a minimum differential pressure to achieve full opening, ensuring dependable operation under varying conditions.
The solenoid coils are encapsulated with high-quality epoxy resin, enhancing durability and protection. When paired with an appropriate cable plug, the valves comply with the IP65 protection class, making them suitable for environments where dust and water ingress are concerns.
This valve is well-suited for handling neutral media such as compressed air and water. Additionally, explosion-proof variants (ATEX certified) are available, allowing safe use in hazardous areas where explosive atmospheres may be present.
