8100 Threaded

The Mercer Valve 8100 Series Pressure Relief Valve is “State of the Art” in soft seat, high flow rate, pressure relievingdevices. The 8100 Series spring operated valve was the first pressure relief valve to incorporate Mercer
Valve’s patented “Auto Seat Technology”® into its design. Our “Auto Seat Technology“® incorporates a fully
guided disk and low rate spring to ensure an accurate and repeatable set pressure. The low rated, guided spring
will reduce stresses on the spring, giving you a consistent, repeatable set pressure, which will continually out
last the competition. The soft seated 8100 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. Our non-rising stem allows us to
produce a valve with a shorter bonnet, which will be lighter and fit in tighter confined spaces.
The 8100 Series is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel
Code, Section VIII, Division 1 for Air/Gas. The 8100 Series is well suited for compressors, separators, transmission,
gathering lines, and other production processes.
