The valve is suited for all industrial air, gas, or liquid relief applications, including compressors, separators, heater treaters, scrubbers, dehydrator, free water knockouts, thermal relief, gas production units, transmission and gathering lines, meter runs, gas plants, chemical plants and other industrial applications.

The soft seat 9100 Series has a field-proven lip seal design, which allows for a tighter seal up to set pressure. This tight seal reduces leaks and limits product loss.
All 9100 Series Threaded Valves are built in accordance with the requirements of the ASME Boiler and Pressure Vessel Code.
