Product Overview
The Q11-16P internally and externally threaded stainless steel miniature one-piece switch ball valve is a forged steel process valve body used by Ruiward Valve Company, with a reasonable structure and beautiful appearance; The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close; The valve stem adopts a bottom mounted structure with reverse sealing, and the valve stem will not be flushed out when the valve chamber is abnormally pressurized.
Unique advantages
- Low fluid resistance, full bore threaded ball valve.
- Simple structure, small volume, and low leakage rate.
- Double sealing surface, good sealing performance, can achieve complete sealing.
- Quick installation, easy operation, quick opening and closing, only need to rotate 90 ° from fully open to fully closed.
- When fully open or fully closed; The sealing surface of the sphere and valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
- Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications from high vacuum to high pressure.
- Due to the wiping property of ball valves during opening and closing, they can be used in media with suspended solid particles.
