Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve, specifically engineered to provide reliable shut-off, dosing, and filling for neutral gaseous and liquid media. To ensure proper valve function, a minimum differential pressure is required. Its design incorporates a vibration-resistant, centrally screwed coil system along with damping features, which contribute to quiet closing and extend the valve’s service life.
The solenoid coils within the Burkert 6281 are moulded using chemically resistant epoxy, enhancing their durability against harsh conditions. To optimize power usage during operation, variants equipped with "Kick and Drop" (KD) electronics assembly — a double coil technology — are available. This innovation helps reduce electricity consumption without compromising performance.
The valve’s standard housing is made from brass, meeting all European drinking water standards. For other markets, a dezincification-resistant brass option is offered to ensure longevity and safety. Additionally, a stainless steel version is available, broadening the range of applications and environments suitable for this valve.
For ease of maintenance and commissioning, the valve can be fitted with a manual override. When combined with an appropriate cable plug conforming to DIN EN 175301-803 Form A, the valves achieve protection class IP65. This ensures reliable operation in various industrial settings. The valve installation is flexible and can be performed in any position, although it is recommended to mount the actuator in an upright orientation for optimal performance.
