 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 unqualified 

personnel may result in improper 

adjustment and unsafe operation. Either 

condition may result in equipment 

damage or personal injury. Use qualified 

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. 

1301 Series High-Pressure 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 fluids 

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.
