peration
When energised, the actuator motor drives a
sector gear and arm assembly, which pushes
down axially on the valve stem against the force of
the return spring. When the actuator is de-
energised, the return spring in the valve brings
back the valve to its normal position. (see “valve
action summary”)

anual Override
The VA-7010 actuator features a manual operating
lever (shown in “Dimensions”) for manually
opening 2-way Push Down To Open valves or
Normally Closed port of 3-way valves. The lever
will not fully close 2-way Push Down To Close
valves or the Normally Opened port of 3-way
valves.

ounting instructions
Observe the following recommendations when
mounting the actuator:
Make sure the actuator is easily accessible for
the electrical connections.
Make sure actuator is free of thermal insulation
material.
Leave at least 25 mm clearance above the
actuator for mounting purposes.
(See “Dimensions”)
To mount the actuator on a VG5000 valve:
1. Place the threaded coupling over the valve
stem on the bonnet.
2. Rotate the actuator to desired position and
tighten the coupling securely by hand.
Note: Never use actuator as a mounting lever.
