M7410E SMALL MODULATING LINEAR VALVE ACTUATOR
MOUNTING POSITION
The actuator may only be mounted beside or above the
valve. Adjust the valve in the correct position before
mounting the actuator.
Fig. 1. Mounting positions
MOUNTING
Before the actuator is fixed to the valve, the adjustment cap
must be removed (Fig. 2). Make sure that the actuator is in
the open position (factory-supplied position) before fixing the
actuator to the valve body.
Fig. 2. Remove protection cap
The actuator must be mounted by hand. Do not use tools or
additional force insofar as this may damage the actuator and
valve.
