DESCRIPTION
Sensitive,
accurate control of reduced pressures is provided by these simple
self-operated pressure regulators. They may be used to control steam
pressures for heating systems, industrial processes and steam-driven
pumps, as well as many other fluid pressure controlling and limiting
applications throughout public buildings, institutions, industrial and
chemical plants, shipboard installations, etc.
When supplied
with reverse-acting valves, these units will open on rising pressure for
modulating pressure relief.
These precisely
designed pressure regulators are ruggedly constructed, using cast iron
alloy of carefully controlled quality for the sturdy frame, molded
diaphragms of Buna-N composition, nylon-reinforced for great flexibility
and long service life.
Cataloged valves
1/2" through 2" are single-seated, stainless steel trimmed for accurate
control on steam applications. The "MA" piston-balanced valves, sizes 3/4"
through 1 1/2", permit pressure drops up to the full valve body rating
without loss of control accuracy. Sizes 2 1/2 through 4" are fitted with
double-seated semi-balanced valves. Double-seated valves are used on
services that do not require "dead-end" shutoff. Body material is bronze
through 1 1/2" size and cast iron 2" and larger.
