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 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.
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 Type 1367 regulator.

Introduction
Scope of the Manual
This manual provides installation information on the
Type 1367 high-pressure instrument supply system.
For complete adjustment, maintenance, and parts
information on the individual components of this
system, refer to separate manuals for the Types 67CF
and 1301F regulators, Type 252 lter, and Type H800
relief valve. Refer to other manuals for actuator, valve
body, and instrument information.
Note
No instruction manual exists for the
Type H120 relief valve, as this relief
valve cannot be adjusted or repaired.
Any maintenance on the Type H120
relief valve must be accomplished by
replacing it as a complete unit.
Product Description
The Type 1367 high-pressure instrument supply
system takes a pressure of up to 2000 psig / 138 bar
and reduces it to a controlled pressure to be used
for supplying a pneumatic instrument. This system
consists of the following lters, regulators, and
relief valves:
• A Type 252 extended body lter with drain valve.
• A rst-stage Type 1301F regulator with mounting
bracket for an actuator yoke or casing.
Maximum Outlet (Supply) Pressure with Type 67CF
Regulator Failed Wide-Open with:
Type H800 Relief Valve Relieving: 50 psig / 3.4 bar
Type H120 (Second Stage) Relief Valve Relieving:
90 psig / 6.2 bar
Temperature Capabilities
-20 to 150°F / -29 to 66°C
Approximate Weight
12 pounds / 5.4 kg
• A Type H120 relief valve mounted in the side outlet
of the Type 1301F regulator.
• A second-stage Type 67CF lter-style regulator,
mounted on the Type 1301F regulator.
• A Type H800 or H120 relief valve nipple-mounted in
the outlet of the Type 67CF regulator.
Principle of Operation
The Type 252 lter helps remove dirt, rust, chips,
scale, and moisture from the incoming high-pressure
supply before it enters the Type 1301F regulator. The
Type 1301F regulator is set to reduce this incoming
high-pressure to 100 psig / 6.9 bar. The reduced
pressure from the Type 1301F regulator is then further
reduced between 20 and 70 psig / 1.4 or 4.8 bar
to supply the pneumatic instrument. Although the
Type 67CF regulator is normally set for 20 psig /
1.4 bar outlet pressure, it can be eld-adjusted up to
35 psig / 2.4 bar outlet pressure.
The rst stage Type H120 relief valve serves to protect
the Type 67CF regulator by relieving if the reduced
pressure from the Type 1301F regulator exceeds
150 psig / 10.3 bar. The Type H800 or H120 relief
valve serves to protect downstream equipment from
overpressure by relieving if the reduced pressure
from the Type 67CF regulator exceeds the relief
setpoint. Air or gas owing from one or both of the
relief valves indicates that one or both of the regulators
are worn or damaged and must be repaired or
replaced immediately.
