ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS
MAY RESULT IN A SAFETY HAZARD.
DESCRIPTION
The Readout Valve is equipped with an integral EPDM rubber check valve designed to minimize system fluid loss when used with a RP250B Readout Probe to monitor pumps, heat exchangers, valves, etc., handling hot or cold water.
CONNECTION SIZE
Readout Valve: 1/8" NPT and 1/4" NPT
Readout Probe: 7/16" – 20 UNF-2A THD Meter Connection
Working Pressure 300 PSIG
Temperature 250°F
INSTALLATION INSTRUCTIONS
WARNING: Hot fluids and/or flu-
id under pressure. Isolate the prod-
uct in which the readout valve is to be installed with shut off valves, or drain the system. Make sure that all drainage from the system has stopped and that the system temperature has cooled to 100° F or less. Vent off any pressure prior to installation. Failure to follow these instructions could result in serious personal injury or death
and property damage.
1. Apply pipe joint compound to NPT end of readout valve body and install into NPT opening.
2. Tighten cap on top of the readout valve.
3. Repressurize the system.
OPERATING INSTRUCTIONS
WARNING: Potential for escape of hot fluids. Use
only B&G companion readout probes to obtain
accurate and safe readout from the readout valve. Failure to follow these instructions could result in serious
personal injury or death and property damage.
WARNING: Hot fluids may escape. When moni-
toring system flow, care must be exercised to
avoid skin or eye contact with liquids that may escape.
Failure to follow these instructions could result in serious personal injury or death and property damage.
1. Connect readout probes to pressure or differential pressure meter with the male thread connection. Make sure
the connection is tight.
WARNING: Hot fluids under pressure. Before
inserting readout probe, slowly loosen the protective cap to vent off any pressure accumulation. The
protective cap must be replaced when readout probe
is removed. Failure to follow these instructions could
result in serious personal injury or death and property
damage.
2. Insert the full length of the probe into each readout
valve and tighten the ferrule nut. It is not uncommon
for a small amount of system fluid to escape during the
insertion.
3. Read pressures according to instructions supplied with
the pressure measuring device.
4. If the measuring device is not to be left permanently
connected to the readout valves, remove the readout
probes from the readout valve and reinstall protective
caps. If left in place, periodically inspect the probes for
leakage and replace if necessary.
SERVICE INSTRUCTIONS
After use, inspect probe for blockage by visual or other
means. Periodically inspect for damage and replace if
necessary.
WARNING: Leakage, corrosion or indications of
damage are signs of an impending serious failure
of the readout valve or readout probe. Periodically
inspect the readout valve or readout probe for signs of
leakage or corrosion. Replace if noted. Failure to follow
these instructions could result in serious personal injury
or death and property damage.
