Samson 3277-5 - Mounting the Actuator Onto the Valve

5-2 EB 8310-1 EN
Installation
Risk of actuator damage due to excessively
high or low tightening torques.
Observe the specied torques when tighten-
ing actuator components. Excessive tighten-
ing torques lead to parts wearing out more
quickly. Parts that are not tightened far
enough may loosen.
Î Observe the specied tightening torques
(uAB0100).
Risk of actuator damage due to the use of
unsuitable tools.
Î Only use tools approved by SAMSON
(uAB0100).
5.2.1 Mounting the actuator
onto the valve
Risk of valve damage or malfunction due to
an incorrectly aligned V-port plug.
On mounting the actuator onto valves tted
with a V-port plug, make sure that the
V-shaped port uncovered rst faces toward
the valve outlet.
Î Read the 'Mounting the actuator onto
the valve' section in the associated valve
documentation.
The valve and actuator are assembled with
special attention paid to the actuator's bench
range and direction of action. These details
are specied on the actuator nameplate (see
the 'Markings on the device' section).
