Expected seating/unseating torque (Nm) including 30% safety factor

To use the torque chart, note the following:

1) Seating/Unseating torque values above included friction bearing torque for stated ∆P.

2) Do not apply a safety factor to above torque values when determining actuator output torque requirement.
