Instruction Manual

Form 589

April 2008

This manual describes and provides instructions and 

parts lists for Type 99 pressure reducing regulators 

complete with standard P590 Series integral filter.  

However, complete instructions and parts listing for the 

Type 1301F pilot supply regulator, and other Fisher

®

 

equipment, such as monitoring pilots will be found in 

separate instruction manuals.

The Type 99 gas regulators provide a broad capacity 

for controlled pressure ranges and capacities 

in a wide variety of distribution, industrial, and 

commercial applications.
A Type 99 regulator has a Type 61L (low pressure), 

Type 61H (high pressure), or a Type 61HP (extra 

high pressure) pilot integrally mounted to the actuator 

casing as shown in Figure 1.  The Type 99 regulator 

can handle up to 1000 psig (69,0 bar) inlet pressures 

(the 1000 psig (69,0 bar) regulator requires a 

Type 1301F pilot supply regulator and a Type H110 pop 

relief valve).  The pilot supply regulator reduces inlet 

pressure to a usable 200 psig (13,8 bar) for the extra 

high pressure pilot.  This regulator comes standard with 

O-ring seals on the guide bushing and valve carrier 

(key 26, Figure 7) to keep main valve body outlet 

pressure from interfering with outlet pressure in the 

lower casing assembly (key 29, Figure 9).

Specifications and ratings for various Type 99 

constructions are listed in the Specifications section 

on page 2.  Some specifications for a given regulator 

as it originally comes from the factory are stamped 

on nameplates located on the pilot and actuator 

spring cases.  A tag (key 159, Parts List) additionally 

may be installed on the pilot to indicate a regulator 

with O-ring stem seal.  These regulators and their 

installations should be checked for compliance with 

applicable codes.
