Produkta raksturojums:
1. the overall body structure welding, there will be no external leakage.
2. the valve seat composed by a PTFE sealing ring and springs which has a strong adapt ability to changes of pressure and temperature, within the using range there will be no any leaks.
3. stem leakage prevention structure, the bottom of the stem has a PTFE seal the puncture, there are two O-rings above, composed of two PTFE gaskets ensure no leakage.
4. the same body material and pipe material, stress will not appear uneven, it will not because of the earthquake and the vehicle passes through the ground sometimes cause extrusion.
5. the body is light and easy to keep temperature not down.
6. we can adjust the body length and stem height according to construction and design requirements of the pipeline.
7. the ball’s machining precision is very high easy to operation, no adverse interference.
8. can use welded and flanged two kinds connection type.
