Mounting The Actuator Onto The Valve - Samson 3323 Mounting And Operating Instructions

NOTICE
!
Risk of valve damage due to the use of
unsuitable tools.
Î Only use tools approved by SAMSON
(u AB 0100).
5.3.1 Mounting the actuator
onto the valve
Î To mount the actuator, proceed as de-
scribed in the associated actuator docu-
mentation.
a) Pneumatic or
electropneumatic actuator
There are two different types of attachment
to mount the pneumatic or electropneumatic
actuator onto the valve depending on the
version (valve size etc.): mounting using
crossbeam or mounting using rods (see
Table 5-2).

Mounting using crossbeam and central nut
When the actuator is mounted to the valve
using a crossbeam (form B, Fig. 5-2), the ac-
tuator is fastened to the valve bonnet using a
central nut.
Mounting using rods
When the actuator is mounted using rods
(form C, Fig. 5-3), the actuator is connected
to the valve bonnet using rods. In this case, a
crossbeam is not required for mounting the
actuator. A plate keeps the correct distance
between rods.
b) Electric actuator
When an electric actuator is mounted onto
the valve, it is mounted with a form-fit con-
nection using a stem connector and yoke.
