Take pressure or temperature readings quickly
These economy plugs will allow you to take pressure or temperature readings
- quickly and eliminate the need for leaving costly gauges or temperature
indicators on the line.
Applications
In general these plugs are a time and money saving device
which is well suited for most plant and pipeline systems and is designed
to eliminate
gauge cocks and thermometer wells. Hot and chilled water systems,
heat exchangers, pumps, differential readings, air, gas lines, and numerous
other applications are only a few of the areas where these plugs
are presently being used.
Valve Materials
Neoprene is a chloroprene based synthetic rubber and
is resistant to deterioration from waxes, fats, oils, greases, petroleum
products,
and most refrigerants.
Nordel is an ethylene-propylene based
synthetic rubber and gives excellent service in hot and cold water
and in some applications
of low steam.
Nordel is resistant to detergents, phosphate esters, ketone,
alcohols, and glycols. It is not suitable for petroleum products.
Neoprene and nordel are proprietary materials and the information presented
herein is believed to be accurate and reliable. We
can assume no liability
for results obtained or damages incurred through the application
of this information. The information is intended as a guide
and if in
doubt ask!
How to Operate
These plugs are permanently installed in the line
at recommended test points. The cap protects the valve and
provides an additional
seal. After the cap has been removed, either a test thermometer
or a gauge
adapter with the proper pressure gauge can be inserted
through the two, self-closing valves in the plug. Readings
are made,
adjustments
or test can be accomplished and when the probes are withdrawn,
the two valves close. The protective cap is then reinstalled.
Tests should
be
made as quickly as possible since the valve reseal time
is
dependent upon time of insertion, time, and pressure.
Slower valve reseal
time can be expected at lower temperature and lower pressures.
Features
- Available in 1/4" and 1/2" NPT sizes
- Available in long length
- Brass body material for non-corrosive service
- Pressure limits to 1000 psi depending on application
- Neoprene core (red cap) for temperature range of 0-200°F, for use with natural gas and petroleum products
- Nordel core (blue cap) for temperature range of 0-275°F, for use with hot and chilled water systems
- Valve core is self-sealing with pressure cup for superior sealing protection
- Tested by an independent lab indicates no leaks at high or low pressure
