KOSO top-guided control valves are compact and simple structured. They are usable in a broad scope of applications, including all cavitation-free liquid services as well as steam and gas services that meet noise regulations.
Aiming at quick delivery and low prices, 551T is limited to JIS 10K, ANSI(JPI)150 lbs. with no optional features. 520T covers minimum flow applications, with its small plug specially designed not to break off.
