JIS 5K Globe Valve
JIS 5K cast iron globe valve features thick cast iron body and bolted bonnet for easy overhaul, the disc trim enables accurate flow throttling better than gate or ball valves. It delivers stable mechanical strength and low manufacturing cost, ideal for non-saltwater general low-pressure pipeline shut-off and regulation.
Overview
Application: Commonly used for cold/hot fresh water, steam and neutral liquid pipelines in factories, municipal water supply and heating systems without seawater corrosion risk. Widely matched with JIS 5K industrial piping, applicable to plant circulating water, building fire protection and low-pressure process fluid control projects.
