Referring to Figure 19 for the proper torque sequence,
torque each screw to 50 in/lbs
7
Using the same sequence, torque each screw to 70 in/
lbs

Portable Regulator Bench Setting
Use the following procedure to change the pressure range for
either the pressure building or economizer regulator.
1
Remove the liquid product from the liquid cylinder.
Vent the liquid cylinder of all pressure.
2 Remove the regulator from the liquid cylinder
3 Place the regulator body in a vise with the bonnet and
adjusting screw pointed up.
4
Back out the adjusting screw until there is no spring
pressure on it.
5 Remove the regulator dome from the body
6
Carefully remove only the spring.
7
Replace the spring and reassemble.
8
See table below for appropriate springs.

Bench Setting an MCR Regulator
1
Connect the pressure control regulator to a nitrogen
pressure source as shown in Figure 20.
2
Connect “EC OUT” (economizer out) port to tee on
“PB OUT” of regulator with a piece of tubing.
3
Close valve “B”. Open valve “D”.
4
Open the pressure source valve (follow appropriate
safety rules).
5
Open valve “C” slowly.
6
Pressure gauge “A” will indicate the pressure to which
the regulator has been set. The pressure can be increased
by turning the adjusting screw in. The pressure may be
decreased by turning the screw out; however, after each
adjustment outward it will be necessary to open and
then close valve “B” to relieve excess pressure.
7 This setting should match the calibrated scale If it does
not, go to step 8.
8
Loosen lock nut “E” and adjust screw “F” until
calibrated scale matches set pressure. When completed,
tighten lock nut “E”. “E” and “F” are only to be
loosened or adjusted during bench setting procedure.
