a) Mounting with brackets: Place coupling on valve stem and the actuator on mounting
bracket. Align valve and actuator in order to eliminate forces on the system; tighten all the
assembly fasteners.
b) Direct mounting: Position the actuator on valve; use caution while inserting the valve
stem into the double square female pinion drive. Insert the screws from the bottom side
of flange and manually tighten them and align the assembly in order to eliminate the
forces on the system; tighten all assembly fasteners.
5. Actuate the unit several times to ensure that it works properly. If the unit does not work
properly, disassemble the unit and repeat steps 1 – 4. If the problem persists, contact
with Genebre, S.A.

stroke through the travel stops to ensure that the valve works properly. GNP actuators
have a regulation range ± 5° in both open and close directions (See Chapter 4 – 3 for
information on actuator positioning phase).
