6. DIRECT/REVERSE ACTION TYPE CONVERSION AND
SPRING RANGE CHANGE OF ACTUATOR
6.1 Direct/Reverse Action Change
As a general rule it is most recommendable to prepare separately the direct type and
reverse type of actuators and not to convert actuators into different types. However,
when it has become unavoidable to convert actuators into other types, conversions
may be done by using the parts mentioned below (Table 6-1 and Table 6-2). The
parts marked “+” are the ones which are newly needed and those marked “-” are
ones which are not used.
