Product Description:
The Burkert 5281 series is a servo-assisted 2/2-way diaphragm solenoid valve engineered to provide dependable shut-off, precise dosing, and efficient filling for neutral gaseous and liquid media. This valve is available in two configurations: normally closed (NC) and normally open (NO), catering to diverse application needs.
Designed with an anti-waterhammer mechanism, the valve ensures smooth operation with minimal noise. It requires a minimum differential pressure to achieve complete opening, guaranteeing reliable performance under appropriate conditions. The solenoid coils are encased in a high-quality epoxy resin, enhancing durability and longevity.
When paired with a compatible cable plug, these valves comply with the IP65 protection class, ensuring resistance against dust and water ingress. The valve is well-suited for use with neutral media, including compressed air and water. Additionally, explosion-proof versions compliant with ATEX standards are available, making the Burkert 5281 series suitable for hazardous area environments.
