133 Series
2
Type Number Description
Type 133H—
High pressure construction for outlet
pressure range of 1.5 to 10 psig (0,10 to 0,69 bar).
The Type 133H can also use the 2-inches w.c. to
2 psig (5,00 mbar to 0,14 bar) springs of the
Type 133L. The maximum operating inlet pressure
is 60 psig (4,14 bar) with a maximum emergency inlet
pressure of 125 psig (8,62 bar).
Type 133HP—
Extra high pressure construction for outlet
pressure range of 2 to 60 psig (0,14 to 4,14 bar). The
maximum operating inlet pressure rating of 150 psig
(10,3 bar) with a maximum emergency inlet pressure of
150 psig (10,3 bar).
Type 133L—
Low pressure construction for outlet
pressure range of 2-inches w.c. to 2 psig (5,00 mbar
to 0,14 bar). The maximum operating inlet pressure
is 60 psig (4,14 bar) with a maximum emergency inlet
pressure of 125 psig (8,62 bar).
Type 133Z—
Zero governor construction for outlet
pressure range of -1 to 4-inches w.c. (-2,00 to
10,00 mbar). The maximum operating inlet pressure is
20 psig (1,38 bar) with a maximum emergency inlet
pressure of 125 psig (8,62 bar).
