Ball Valve Stem

1. Zhiyuan valve lever thread uses the self-made extrusion, The thread intensity is high, Precision

2. The thread spot and the light pole spot concentric is consistent, Overcame the long-term puzzle domestic to roll in the silk craft to be easy to twist, vulnerably to roll the silk mold the question

3. The light pole spot uses the patent technology precision to achieve the mirror surface effect, Opens shuts with ease, The leak-proof quality is good

4. Pours closes the spot to use the numerical control technology time to take shape, The precision is high, Pours the optical density to seal the performance to be good

5. The end spot T die uses the forging and stamping to take shape the craft, The efficiency is high, The cost is low

6. The valve lever entire wrap production craft achieves the international advanced level
