Type 1367 High-Pressure Instrument Supply
System with Overpressure Protection
INLET

Figure 1. Type 1367 High-Pressure Instrument Supply System
Introduction
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.
• 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.
Features
• Regulation and Overpressure Protection in
One Complete Package — This system provides
two-stage pressure reduction with a non-adjustable
relief valve matched to each regulator.
• Installation Flexibility — The Type 1367 system
can be ordered for mounting on either the yoke or
casing of an actuator.
• NACE Capabilities — For sour gas applications,
the Type 1367 system is available in materials
that comply with the recommendations of NACE
International standard MR0175.
• Capability for Continuous Moisture Removal —
The drain valves can be removed from both the
Type 252 lter and the Type 67CF lter-style
regulator, and tubing installed to provide
continuous drains.

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 the incoming
high-pressure to 100 psig / 6.9 bar. The reduced
pressure from the Type 1301F regulator is then further
reduced to 20 or 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 70 psig /
8.4 bar outlet pressure.
The rst stage Type H120 relief valve helps 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 helps protect downstream equipment from
overpressure by starting to relieve if the reduced
pressure from the Type 67CF regulator exceeds the
relief valve 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.
Ordering Information
When ordering a Type 1367 high-pressure
instrument supply system, specify the type number,
the pressure setting required, any construction
material variations desired, and whether yoke or
casing mounting is required.
