rotork IQT User Manual

IQT actuators are designed to stop at
the end of travel by torque limitation
against the actuator stop bolts. Stop
bolts should therefore be set to the
precise stopping position required, refer
to section 5.6.
IQTF actuators can be configured to
close on torque or limit. Refer to valve
manufacturers instructions.
Refer to valve manufacturer
for recommended setting.
