NENUTEC AG offers advanced actuator solutions. One is wafer-type NBFV 8000 butterfly valves motorised with actuator series NEAA and FSAA (EFS®). EFS® (Electronic Fail Safe) technology allows movement to the desired safety position during power interruptions. Data centers and cooling towers, for example, are a popular area of application for such actuators. The combination NBFV/FSAA helps a user to reduce the energy consumption by up to 90% compared to traditional solutions.
NBFV 8000 series selection table enables a user to easily select the NBFV valve and the appropriate NEAA/FSAA actuator for their application.
The NBFV8000 butterfly valve has several benefits. Firstly, it has a light-weight aluminium body, shaft SS420, disc of nodular iron GJS500, seat in EPDM and stainless steel stem circlip. Also, flow media is completely isolated from top flange. There is a synchronised rotation between stem and disc decreases operation torque and ensures a long useful life. Shaft mounting with specifically designed NENUTEC bracket set which guarantees concentric rotary movement and includes a quality handle for manual operation.
