3.1 Fitting the actuator (extend) to the valve
-
Remove the screw and nut (
13
and
14
) then the rear and front clamp (
11
and
12
).
-
Ensure the indicator scale is facing the same way as the valve name-plate.
-
Apply the control signal pressure to the bottom of the actuator to bring the spindle (
19
) to the mid-travel
position.
-
Manually push the valve spindle down to ensure that the plug is on the valve seat.
-
Screw the yoke adapter (
35
) onto the valve and tighten it to 50 Nm (36.9 lbf ft) - (TN2 _ _ _ E_ only).
-
Put the yoke sleeve (
36
) onto the valve bonnet (TN2 _ _ _ EC only).
-
Locate the actuator yoke onto the valve bonnet and fit the lock-nut (
A
).
-
Screw the lock-nut of the valve’s spindle down to the lowest part of the valve spindle.
-
Screw the bottom connector (
29
) onto the valve spindle, caution there must be no valve spindle threads
above the bottom connector.
-
Loosen the lock-nut and screw the connector (
20
) upwards 3 turns, then remove the air supply.
-
Apply the minimum signal pr 0.1 bar (1.45 psi) maximum to the bottom of the actuator, and then
adjust the connector (
20
) so that it touches the bottom connector (
29
), then tighten the lock-nut (
15
).
-
Release the control air signal. Fit the front and rear clamps (
11
and
12
).
-
Fit the locking screws and nuts (
13
and
14

-
Operate the actuator and valve over its full travel four times to ensure alignment.
-
Tighten the mounting nut to 50 N m (36.9 lbf ft).
