Warning To avoid pressure shocks on the butterfly valve, the VKF41.. must be driven to its fully open position (either manually or via positioning signal Y1) prior to activating the pump(s). Mounting notes The Mounting Instructions 4 319 8927 0 are enclosed in the product packaging. VKF41.. butterfly valves can be mounted in PN 6, PN 10, PN 16 applications. Orientation Upright to horizontal 90° 4716Z16 90° The valve, actuator and mounting set are easily assembled directly on site.
