BRAND : Fisher
Fisher CAV4 valves are designed for clean, cavitating services where the pressure drop is above 207 bar (3000 psi). The Cavitrol™ IV trim in this valve is designed to have an expanding flow area. Each of the trim stages has a successively larger flow area. The result is a very efficient operation because more than 90 percent of the overall pressure drop is taken in the initial stages, where there is little danger of cavity formation which could result in cavitation.
