Introduction
Scope of the Manual
This manual provides instructions for the installation,
adjustment, maintenance and parts ordering
information for the Type HSR residential and/or
industrial/commercial pressure regulator.
Description
The Type HSR direct-operated, spring-loaded regulators
with internal relief provide economical pressure
reducing control in a variety of residential, commercial
and industrial applications. These regulators can be
used with natural, manufactured or lique ed petroleum
gases. In addition, the Type HSR regulator has
internal relief across the diaphragm to help minimize
overpressure. Any outlet pressure above the start-to-
discharge point of the nonadjustable relief valve spring
moves the diaphragm off the relief valve seat, allowing
excess pressure to bleed out through the screened
spring case vent.
