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 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.
