!
Failure to follow these instructions or
to properly install and maintain this
equipment could result in an explosion
and/or fire causing property damage
and personal injury or death.
Fisher
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. 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 qualified person must
install or service the regulator.
Introduction
Scope of the Manual
This Instruction Manual provides installation,
maintenance, and parts ordering information for the
Type 310A-32A pilot-operated, pressure reducing
regulator and the Type 310A-32A-32A working monitor
regulator. Information on equipment used with this
regulator is found in separate manuals.
Description
The Type 310A-32A pilot-operated, pressure reducing
regulator includes a single Type 32A pilot mounted
on the Type 310A main valve for pressure reducing or
wide-open monitoring applications.

Figure 1. Type 310A Regulator with Type 32A Pilot
The Type 310A-32A-32A working monitor regulator
includes Type 310A regulator which functions as the
first-stage regulator in the working monitor situations
by taking the initial pressure reduction and two
Type 32A pilots which serve as the monitoring and
working pilots.
Specifications
Ratings and specifications for the Type 310A
configurations are listed in the Specifications section
on page 2. Some specifications for a specific regulator
are stamped on a nameplate attached to the pilot
spring case (key 1, Figure 9).
