INTRODUCTION
Scope of the Manual
This manual provides instructions for the
installation, adjustment, and maintenance for
the Type B95 pressure regulator.
© 2020 Emerson. All rights reserved.
DESCRIPTION
The Type B-95 is a fully automatic pressure
reducing valve designed to reduce a high inlet
pressure to a lower pressure and maintain the
lower pressure to reasonably close limits. Also
available in a cryogenic version, it is ideal for
use in the pressure build-up circuit, for either
liquid oil or gas service.
Steel or stainless steel bodies and chambers,
stainless steel trim. Choice of metal, Teflon or
Buna-N seating. Buna-N diaphragm (limited to
180°F) or Stainless steel laminated diaphragms
(to 450°F). Cryogenic version incorporates
Stainless steel pressure spring, cap screws,
and adjusting screw and lock nut.
INSTALLATION INSTRUCTIONS
The Type B-95 regulator may be installed
in the horizontal positon with the spring
chamber up or down. For other installation
requirements, consult the factory. For ease
of operation and maintenance, it is suggested
that manual shutoff valves be installed
upstream and downstream from the valve.
Before installing the valve, all piping should be
thoroughly flushed out to remove any foreign
material. Install the valve with the inlet pipe
fitted to the inlet connection identified on the
valve body. Use a compatible sealant on the
male pipe threads and do not overtighten the
valve connections.
