Marine Threaded Ball Valve | Quick Rotating Cut Off Device
A compact pipeline valve utilizing spherical opening and closing parts.
Rotating just 90 degrees achieves rapid media cut off functions.
Connections stay tight and reliable, and subsequent disassembly and replacement remain quite convenient.
Accreditation and Certificates:
Threaded ball valves gain wide popularity among shipowners due to low fluid resistance and small physical size.
Operators control flow directions or cut off media precisely just by rotating 90 degrees easily.
Products divide into one piece, two piece, and three piece multiple structures.
Core material options include cast steel, stainless steel, and copper.
This model withstands high temperature environments up to 300°C with extreme stability.
It performs especially well in corrosive pipelines within marine chemical transport systems.

- Lightweight structure: Small volume and light weight, combined with simple structure, widens the application range greatly.
- High temperature tolerance: Handles up to 300°C high temperature steam or oil safely.
- Tight and reliable: Threaded connections provide tight and reliable anti-vibration performance, preventing vibration loosening.
Applications：
- Marine piping systems: Controls the on/off state of key media like water, steam, and oil rapidly.
- Chemical and Ship Chemical Transportation System: Uses stainless steel materials to handle corrosive media like nitric and acetic acids safely.
Installation & Maintenance：
Installers must check and fasten threaded connections evenly, preventing unexpected loosening caused by ship vibration.
Routine maintenance work requires thorough inspection and replacement of aged seal ring components.
Custom Options Available：
Offers different structural choices from one piece to three piece and supports special anti corrosion alloy material customizations. We provide customization services based on international standards such as ANSI, JIS, and DIN, ensuring compatibility with different global market requirements.
