At tank pressure less than 80% of set

pressure, upper dome pressure should be

about equal to tank pressure and the vent

should be bubble tight. Minimal leakage

may occur between 80% and 90% of set

pressure.

At set pressure, the upper dome pressure

should be less than 50% of set pressure

and the vent should be flowing freely.

At 110% of set pressure, the lower dome

pressure should be greater than 75% of

set pressure, the upper dome should be

less than 10% and the vent should show no

leakage. The vent should be bubble tight

above 110% of set pressure.

Figure 2

When all conditions have been met, install

the pilot on the valve by connecting the

tubing to the sense, upper dome and

lower dome ports. When pressure is

applied to the valve, test all connections

with a soap solution.
