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.
