Cash Valve Type PBE-5 Pressure Builder/Economizer Regulator Owner's manual
Cash Valve Type PBE-5 Pressure builder/economizer regulator
Installation and Maintenance Instructions
Before installation these instructions must be fully read and understood
General installation instructions
Maintenance instructions
For ease of operation and maintenance, it
is suggested that 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.
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 or the
regulator. Before proceeding with any valve
service be certain to relieve the pressure from
both sides of the regulator.
Construction
See component description for materials of
construction.
Operating instructions
Refer to section view above for parts
identification. Repair parts can easily be installed
without removing the regulator from the line.
Adjusting the pressure build set pressure:
Description
The type PBE-5 regulator is a fully automatic
pressure building/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 incorporates a check valve
to prevent backflow into the economizer. An
indicating adjustment screw provides an easy
field adjustment reference.
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.
