Introduction
Scope of Manual
This manual describes and provides instructions and
parts lists for the Type 67, 67H, 67HR, 67R, 67SS, and
67SSR regulators without filters. These regulators
usually are shipped separately for line or panel mount-
ing, although sometimes they are shipped installed on
other equipment. Instructions and parts lists for other
equipment, as well as for other 67 Series regulators not
covered in this manual, are found in separate manuals.
Product Description
Type 67, 67H, 67HR, 67R, 67SS, and 67SSR self-
operated, small-volume regulators (figure 1) provide
constant reduced pressures in a variety of applications.
Although most of these regulators may be used only
with air or other gases, or certain liquefied gases, those
with brass or stainless steel bodies additionally may be
used for water and similar liquid service.
A Type 67HR, 67R, or 67SSR regulator has an integral
low-capacity internal relief valve. In these constructions,
the stem seats against a soft-seated orifice in the
diaphragm assembly. A downstream pressure increase
above the outlet pressure setting moves the diaphragm
assembly off the stem, venting the excess pressure
through a hole drilled or tapped in the spring case.
Specifications
Table 1 gives some general Type 67, 67H, 67HR, 67R,
67SS, and 67SSR regulator ratings and other specifica-
tions. A label on the spring case gives the recom-
mended and actual control spring range for a given
regulator as it comes from the factory.
