The 72000 Series is designed for precise capacity control, while efficiently minimizing noise and outlet velocities using single or multiple cages or V-Log trim. Specific applications: compressor antisurge flare to atmosphere	The 77000 Series multi-stage, expanding area control valve is designed primarily for high-pressure compressible fluid or 2-phase flow applications. It effectively controls erosion, de-gassing, and high noise levels. Specific applications: hot separator letdown, well head choke	The 18400 & 78400 Series valve used on liquid services eliminate cavitation. Specific applications: boiler feed water recirculation desuperheater spray water
