For an FE AND FK butterfly valve, DN100mm, the maximum torque at maximum working pressure (PN10) is 40Nm. This figure described the force required to open or shut the valve, and is used to determine which actuator (automatic control system) is required. Torque rating for butterfly valves can be found on the FIP FE or FK specification sheets located in the Technical Library of this website.
