4.1 Notes on installation
− The valve must be installed in the upright
position with the actuator on top.
For valves with welding ends, after loosening
the clamp (5.4), remove the entire valve con-
struction from the valve body before welding
it into the pipeline.
− Make sure the valves are installed free of
stress. Check to ensure the plug stem
moves smoothly.
− Flush the pipeline thoroughly before in-
stalling the valve.
− If the valve bonnet is designed for con-
nection to a steam line, connect the com-
pression-type ttings to the steam supply
line.
A pressure in the steam line connection
(steam or sterile uid) that is higher than the
pressure in the valve itself may affect the
process medium inside the valve due to it be
mixed with the steam (or sterile uid).
Observe the relevant hygiene regulations.
For compliance with 3-A regulations, a
gasket according to the recommendations of
the 3-ASanitary Standards Inc.
(uBulletin2011-3 at
uhttp://www.3-a.org) is required for a
Type3347 Valve with threaded connections
according to DIN11851/DIN11887.
4.2 Signal pressure line
Connect the signal pressure line for valves
with actuator with fail-safe action "actuator
stem extends" to the connection on the bot-
tom diaphragm case, and for valves with ac-
tuator with fail-safe action "actuator stem re-
tracts" to the connection on the top dia-
phragm case.
In the Type3277 Actuator, the lower signal
pressure connection is located at the side of
the yoke under the bottom diaphragm case.
