Service- and media factor - Actuator Sizing
*Valve is completely closed and opens 2 times a day minimum.
** Valve is completely closed and opens only one time per week or longer. Having a long period without
maneuvering the valve, will increase the breakaway torque.
NB: Please maneuver the DVC butterfly valve at least one time per month to avoid deformation of the
rubber seat.
EXAMPLE OF ACTUATOR SIZING:
Simple ON/OFF operation, Medium: Molasses, Valve: 2231 DN100.
1.15[SF] x 1.30[MF] x 34[Nm] =
50.8Nm
(Sizing torque actuator)
Only choose one Service Factor
[SF]
and one Medium factor
[MF]
when calculating the sizing torque.
