Threaded Ball Valve for Small Bore Pipeline Shut-Off
A threaded ball valve is a quarter-turn shut-off valve with screwed end connections such as NPT, BSPT or BSPP. Compared with flanged ball valves, it is more compact and easier to install in small-diameter pipelines, skids, equipment packages and utility systems.
As a threaded ball valve manufacturer, ZONCIC focuses on practical industrial supply: stable body material, accurate thread machining, dependable seat sealing, pressure testing and export packing. Buyers can choose stainless steel, carbon steel or forged steel construction according to media, pressure and working environment.
For larger pipeline sizes or project pipeline service, you can also review our flanged ball valve and trunnion ball valve solutions.
Why Buyers Choose Threaded End Ball Valves
Compact Installation
Threaded end ball valves are suitable for limited-space systems, small bore pipework and equipment assemblies where flange connection is not required.
Fast Maintenance
Screwed end connections allow convenient installation, replacement and maintenance for utility, water, air, gas and light industrial service.
Flexible Material Options
Available in CF8, CF8M, WCB, A105, F304, F316 and alloy materials for different media and working conditions.
