Versions - Samson 3273 Mounting And Operating Instructions

Design and principle of operation
For mounted SAMSON globe valves
The handwheel is marked 'Open/Close' and
has directional arrows.
− Turn the handwheel clockwise: the globe
valve closes.
− Turn the handwheel counterclockwise: the
globe valve opens.
For mounted SAMSON three-way valves
A label is affixed to the handwheel, which
indicates in which direction the threaded rod
is moved when the handwheel is turned (see
Fig. 4).
The gear is locked by the locking bolt to pre-
vent accidental adjustment.
