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.
