Isolation Valve Models 8000F and 8000T
are designed to incorporate two safety
relief valves to protect in an overpressure
emergency. Only one safety relief valve is
in operation at a time, while the other is a
back up. If a problem occurs, such as a
leak, simply switch to the other alternate
safety valve. Remove the faulty valve and
make repairs. This insures that one safety
relief valve is in operation at all times.
