WARNING

!

Failure to follow these instructions or
to properly install and maintain this
equipment could result in an explosion,

re and/or chemical contamination

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 Fisher 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.

Installation, operation, and maintenance

procedures performed by unqualied

personnel may result in improper
adjustment and unsafe operation. Either
condition may result in equipment

damage or personal injury. Use qualied

personnel when installing, operating,
and maintaining the 1301 Series
high-pressure regulator.

Introduction

Scope of the Manual

This Instruction Manual provides instructions for
the installation, adjustment, maintenance, and
parts ordering of the Types 1301F and 1301G
high-pressure regulators.

Product Description

Types 1301F and 1301G regulators are direct-operated,
high-pressure regulators, which can be used where
high-pressure gas must be reduced for use as pilot
supply pressure in pilot-operated regulators or as
loading pressure in pressure-loaded regulators.

Types 1301F and 1301G regulators can also be used
in many other applications due to their rugged design

as high-pressure reducing regulators for various uids

such as air, gas, water, and other liquids.

The Type 1301F can handle outlet pressures from 10 to
225 psig (0,69 to 15,5 bar) in three ranges and the
Type 1301G can handle outlet pressures from 200 to
500 psig (13,8 to 34,5 bar) in one range.

Principle of Operation

The 1301 Series regulators are direct-operated.
Downstream pressure is registered internally through
the body to the underside of the diaphragm. When
downstream pressure is at or above set pressure,

the disk is held against the orice and there is no
ow through the regulator. When demand increases,

downstream pressure decreases slightly allowing the

2

regulator spring to extend, moving the yoke and disk

assembly down and away from the orice. This allows
ow through the body to the downstream system.

As the downstream pressure reach its setting, it started
to overcome the spring force which is sense by the
diaphragm, moving the yoke and disk assembly up and

near its orice, restricting the ow across the regulator.
