CROSBY SERIES 82 PRESSURE RELIEF VALVES

High performance, direct spring operated pressure relief valve for natural gas applications

FEATURES • Leak-tight performance near set pressure allows higher operating pressures resulting in increased process throughput and system optimization. • 2-piece body design with easily replaceable seat and seals reduces downtime and maintenance costs. • FKM soft seat provides repeatable leak-tight performance before and after each relief cycle. • Bubble tight at 90% or better of set pressure. • Manufactured to ASME Section VIII UV for gas service. • Relieving capacities certified by National Board of Boiler and Pressure Vessel Inspectors. • Standard trim components in 316 stainless steel for maximum corrosion resistance. • Optional trim to NACE MR-0175 (2002 Edition). • Gas service only. Lift lever not available for air service.

GENERAL APPLICATION
