4.
Fit the control top (B) over the switch bar (1) onto the installation base and
push until stop. For optimum assembly the O-ring (31) should be slightly
greased.
5.
Turn the control top into the required position and tighten the clamping base
(15) and screws (15) with a torque of 1 Nm (base/ installation base).
On FLOWVENT valves, internal air guiding is not possible!
6.
Therefore, use an air hose (L) to connect the air connection (Y1) on the
control top with the connection Y1 on the valve actuator. In the case of a
FLOWVENT valve and control tops with lift stroke, connect the air
connections Y2 and Y3 to the connections Y2 and Y3 of the valve actuator. In
the case of valves with air assist, connect Y2 to connection Y2 of the valve
actuator (see hose connection plan of the valve).
7.
Perform commissioning, see Chapter 6, Page 41 and Chapter 7, Page 67.
8.
Fit the hood and tighten the screws to 1 Nm.
®
Done.

2.0, M_0(06), MT/T_R(08)
Requirement:
•
Pay attention not to kink the air hoses when mounting the control top.
Carry out the following steps:
1.

4.1 of the actuator A.4, torque 2 Nm (1.4 lbft).
Fig.28
2.
Insert the switch bar (1) through the sliding piece into the piston rod A 4.1 and
tighten with an open end spanner (a/f 13) at 1.1 (22 Nm).
3.
Fit the control top (B) over the switch bar (1) and on the actuator.
