Product Description:
The Burkert 5281 series represents a servo-assisted 2/2-way diaphragm solenoid valve engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid substances. This valve is offered in two configurations: normally closed (NC) and normally open (NO), catering to a variety of application needs.
Designed with an anti-waterhammer mechanism and a low-noise operation, the valve ensures smooth and quiet functioning. It requires a minimal differential pressure to achieve full opening, enhancing its efficiency in different systems. Additionally, the solenoid coils are encapsulated with high-quality epoxy resin, providing durability and protection.
When paired with an appropriate cable plug, these valves attain an IP65 protection rating, ensuring resistance against dust and water ingress. They are well-suited for handling neutral media, compressed air, and water, making them versatile in multiple industrial environments.
For use in hazardous areas, explosion-proof versions compliant with ATEX standards are also available, guaranteeing safety and reliability under demanding conditions.
