Detail
Handle Ball / Integral Stem Valve Ball
The handle valve ball is specially designed for manual ball valves. It features an integral square stem on the top of the ball, which directly connects with the operating handle. The ball is rotated manually to open or close the valve, widely used in small and medium bore, low pressure and normal temperature pipelines.
Structure Features
- Integrated square shaft on the ball top, no separate valve stem needed.
- Compact one-piece structure, easy installation and lower assembly cost.
- Mostly floating ball design, achieving sealing by medium pressure pushing against the valve seat.
- Available in straight port, L-port and T-port types for 2-way and 3-way manual ball valves.
-
Material & Process
Main materials: 201, 304, 316L, 443 stainless steel.Made by forging or investment casting, CNC precision machined and mirror lapped for tight sealing. Both soft seat and metal hard seat types are available.Key Advantages
- Integrated stem design simplifies assembly and reduces parts cost.
- Cost-effective and economical for general industrial and civil pipelines.
- Low operation torque, easy manual control.
- Stable sealing performance, good resistance to water, gas and oil corrosion.
- Full size range suitable for DN15–DN100 manual ball valves.
Applications
Water supply and drainage, gas pipeline, HVAC, air compressor system, general industrial water/gas/oil lines and mechanical equipment supporting valves。
