Jordan Valve 1051M Series Rotary Actuator - Manual (Page 3)

Loading Connection
1. Connect the loading pressure piping to the
pressure connection in the top of the
diaphragm casing. Run either 1/4-inch
pipe or 3/8-inch tubing between the 1/4-inch
pressure connection and the instrument.
2. Keep the length of pipe or tubing as short as
possible to avoid transmission lag in
the control signal. Should a volume
booster or valve positioner be used, ensure that
it is properly connected to the factory.
If a valve positioner is part of the assembly, the
connection will l ikely be made at
the Jordan Valve factory.
3. When the control valve has been completely
installed and connected, check for correct ac-
tion (air-to-open or air-to-close) according to
the controlling instrument. Ensure proper opera-
tion by checking that the actuator stem
and valve shaft are moving freely in
response to the loading pressure
change on the diaphragm.
