pressure balance valve assembly.

Step 2 –

nstall a valve to the inlet port on the

ressure balance valve assembly.

Step 3 –

Install a tee fitting to the rear of the

AVC unit.

Step 4 –

Connect a pressure standard, for exam-

ple a dial gauge or digital indicator to

one side of the tee. To the other side

of the tee connect the device to be

calibrated or tested.

⁄8 NPTF ports.

PERATION

Step 1 –

Open the pressure balance valve.

Step 2 –

Open the vent valve.

tep 3 –

urn the control knob to approximately

midrange. This will allow for increase

and decrease of system pressure.

Alternatively, the starting position of the

knob may be at the counterclockwise

or clockwise stop. This will allow for

maximum pressure increase (knob at

the counterclockwise stop) or maximum

pressure decrease (knob at clockwise

stop).

Step 4 –

Close the vent valve.

Step 5 –

Open the inlet v

alve to provide pressure

to approximately the desired pressure

level.

Step 6 –

When the appropriate pressure has

been achieved, close the inlet valve.

Step 7 –

Close pressure balance valve.

Step 8 –

Turn control knob clockwise to increase

system pressure or counterclockwise to

decrease system pressure.

NOTE (Operation) –

During operation the pressure balance

valve will automatically open if the pres-

sure across the piston exceeds safe

levels. This is factory set at a nominal

pressure differential of 150 psi.
