Cash Valve Type PBE-5 Pressure Builder/Economizer Regulator Installation guide
CASH VALVE TYPE PBE-5 PRESSURE BUILDER/ECONOMIZER REGULATOR
INSTALLATION INSTRUCTIONS
Before installation, these instructions must be read carefully and understood
DESCRIPTION
CONSTRUCTION
The Type PBE-5 regulator is a fully automatic
pressure builder/economizer valve designed
for cryogenic liquid systems. It is equipped with
a non-adjustable/fixed set point economizer.
The valve is also equipped with bullnose tube
connections that optionally incorporates
a check valve to prevent backflow into the
economizer. An indicating adjustment screw
provides an easy field adjustment reference.
See component description for materials of
construction.
SPECIFICATION DATA

Sizes: 0.839" diameter 316L SST Tube
Connections: SST Bullnose Tube/Union Nut
½ internal NPT
Body material: ASTM CA377 Brass Forging
Temperature rating:
-320°F (-196°C) to +150°F (66°C)

consult the factory.
GENERAL INSTALLATION INSTRUCTIONS
For easy operation and maintenance, it is
suggested that the manual shut-off valves be
installed upstream and downstream from the
valve. Before installing the valve, the piping
and valve should be thoroughly flushed out to
remove any foreign material. The maximum
torque to apply to the union nut is 80 ft-lbs.

OPERATING INSTRUCTIONS
Adjusting the Pressure Build Set Pressure
To increase the set pressure, turn the adjusting
screw clockwise (into the spring chamber).
To decrease the pressure, turn the adjusting
screw counter-clockwise (out of the spring
chamber).
The Economizer Set Pressure is fixed.
The Economizer will begin to open between
approximately 8-11 psi above the Pressure
Build set point.
MAINTENANCE INSTRUCTIONS
CAUTION
Before attempting to replace any spare parts,
be sure to shut off all pressure connections to
the valve. With the valve closed however, system
pressure could still be locked between the shut
off valve and the inlet and/or outlet sides of the
regulator. Before proceeding with any valve
service, be certain to relieve the pressure from
both sides of the regulator.
Refer to section view on the following page for
parts identification. Repair parts can easily be
installed without removing the regulator from
the line.
