Product Description:
The Burkert 5281 series represents a servo-assisted 2/2-way diaphragm solenoid valve that is engineered to provide dependable shut-off, precise dosing, and efficient filling for neutral gaseous and liquid substances. This valve is offered in two configurations: normally closed (NC) and normally open (NO), catering to various operational needs.
Designed with an anti-waterhammer mechanism, the valve operates with minimal noise, ensuring smooth performance. It requires a certain minimum differential pressure to achieve a fully open position, enhancing its reliability in different applications. The solenoid coils are encapsulated using premium-quality epoxy resin, which provides robust durability and protection.
When paired with an appropriate cable plug, the Burkert 5281 valves comply with the IP65 protection rating, offering solid resistance against dust and water ingress. This makes the valve highly suitable for handling neutral media, including compressed air and water, across a variety of environments.
Furthermore, for applications in hazardous areas, explosion-proof versions compliant with ATEX standards are available, ensuring safety and reliability where it matters most.
