8000

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.
