The actuators provide fastening holes of different dimension to facilitate
mounting on different types of valves, see details in
on page 35
and
on page 36.
When the actuator and valve do not have a natural match, it is necessary to
use an adaptor. Various adaptors are available, but the two most common
ones are the square reducer and the stem adapter. When buying
actuator and valves together from Eltorque, this is handled by our project
personnel. If you order just the actuator, take care to verify the critical
dimensions and whether the valve has a parallel or standard configuration.
Square reducers might be necessary. Always use two pieces with QT250. The
QT800 only has room for one. The type of reducer to be used depends on
the valve type - please contact your Eltorque representative or Eltorque
support for further details.
