Mounting the control top to different valves
This chapter describes how the control top is installed and removed on actuators
of different valve types. Observe the following notes when doing so.
Notice
The vent plug E2 is a safety element.
If the element is not installed correctly or if the vent is covered, the safety
function is no longer guaranteed.
► The installation position of the vent plug E2 must never be pointing
vertically upwards.
► The vent plug E2 must never be covered.
6.6.1
Mounting to a VARIVENT Valve
This chapter describes how the control top is installed on VARIVENT single and
double-seat valves (also with lifting actuator). The instructions do not apply to
installation on VARIVENT double-seat valve types R, T_R, M/2.0, M_0(06), MT/
T_R(08) with lifting actuator. This installation is described below in the chapter
"Installation on VARIVENT double-seat valves with lifting actuator type R, T_R,
M/2.0, M_0(06), MT/T_R(08)" (CROSS REFERENCE).

Requirement:
•
Pay attention not to kink the air hoses when mounting the control top.
Carry out the following steps:
1.
Check that the switch bar (1) is firmly in place. If necessary, tighten using an
a/f 13 open end spanner; torque 2 Nm (1.4 lbft).
2.
Fit the control top (B) over the switch bar (1) and on the actuator (A.1).
3.
Tighten the clamps (15) and screws (39) to a torque of 1Nm (0.7 lbft).
4.
Align the pneumatic and electrical connections in accordance with the valve
block configuration.
5.
Close the air connection Y1 with a sealing plug (23) since the control top
T.VIS A-15 has an inner air duct.
