Valve/Actuator assembly:
A) Direct mounting.
Valve actuator Direct mounting is the best solution to avoid plays between valve stem and actuator drive shaft. For a direct mounting
you should have the same standard flange connection on valve and actuator as well as the valve stem dimensions that fit perfectly
with the actuator drive. Before installation please verify that the actuator and valve flange ISO connections are the same size; verify
that the valve stem size and shape is suitable for direct mounting, if necessary, use a drive reduction.
Fit the valve stem into the actuator drive shaft connection, and bolt together the two ISO flanges.
B) Mounting plate connection.
In case direct mounting is not possible cause of little differences in actuator/valve flanges or drives sizes, mounting plates adapters
with suitable flanges dimensions allows an easy connection living a sufficient space for the valve/actuator drive adapter.
C) Bracket & Joint connection.
Wherever for technical reason the plant installation requires a distance between actuator and valve, or the valve flange and/or stem
are not standard, and in any case, where the valve/actuator connection could not be possible, a bracket and joint is the right answer.
The Bracket is a steel bridge that allows to connect the valve with is own flange connection in one side and with the suitable actuator
connection onto the opposite side, living a space in between for a steel joint connection. The joint allows a drive connection between
the actuator and the valve stem indispensable in case of stem key drive and flat head.
Chose the suitable flange bracket and the required joint connections to fix the actuator onto the valve very tight without any plays.
ACTUATECH actuator with its draining channels system on the flange connection pattern is especially designed for valve
direct mounting. This system allows to drop away any possible flow coming from the valve stem that with valve/actuator
direct mounting could damage the actuator.
