regulators must be installed,
operated and maintained in accordance
with federal, state and local codes, rules
and regulations and Emerson Process
Management Regulator Technologies, Inc.
(Regulator Technologies) instructions.
If the regulator vents gas or a leak
develops in the system, service to the unit
may be required. Failure to correct trouble
could result in a hazardous condition.
Call a gas service person to service the
unit. Only a qualied person must install
or service the regulator.
Introduction
Scope of the Manual
This Instruction Manual provides installation, adjustment
and maintenance instructions and parts ordering
information for the 299H Series regulators. Complete
instructions and parts list for the 67C Series ltered pilot
supply regulator and other Fisher equipment are found
in separate instruction manuals.
Description
The 299H Series pressure reducing regulators provide
a broad capacity of controlled pressure ranges and
capacities in a wide variety of distribution, industrial
and commercial applications. A 299H Series regulator
has a pilot integrally mounted to the actuator casing.
The 299H Series regulators can handle inlet pressures
up to 175 psi / 12.1 bar depending on orice size.
Figure 1. 299H Series Pressure Reducing Regulator
The integral token relief on the Types 299HR and
299HSR regulators is located in the pilot and opens
to relieve minor overpressure.
The Type 299HS provides overpressure or overpressure
and underpressure protection by completely shutting off
the ow of gas to the downstream system. It comes with
a Type VSX-2 slam-shut device which can be congured
for Ovepressure Shutoff (OPSO) or Overpressure and
Underpressure Shutoff (OPSO/UPSO). The slam-shut
device’s actions are independent of the main valve and
of variations to the inlet pressure. The Type VSX-2
slam-shut device has internal or external registration.
External registration requires a downstream sensing line.
