Mountingtypes
There are two types of mounting depending on the valve/actuator combination: mounting using a crossbeam or mounting on rods.
When the actuator is mounted to the valve using a crossbeam (Form B, Fig.8), the actuator is fastened to the valve bonnet using a
central nut.
When the actuator is mounted on rods (Form C, Fig.9) the actuator is connected to the valve bonnet using rods. In this case, a
crossbeam is not required for mounting the actuator.
