Introduction Scope of Manual
gases, or certain liquefied gases, those with brass or stainless steel bodies additionally may be used for water and similar liquid service.
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 mounting, 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.
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
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
Table 1 gives some general Type 67, 67H, 67HR, 67R, 67SS, and 67SSR regulator ratings and other specifications. A label on the spring case gives the recommended and actual control spring range for a given regulator as it comes from the factory.
