Specification of PTFE lined corrosion-resistant ball valve
Unique Characteristics
- Fluid resistance is small, high corrosion resistance — lining of fluorine ball valve is smooth,smooth flow channel, minimum pressure loss.
Apply to regular operation, switch is quick and convenient, Just turn the ball 90 degrees and complete the opening and closing action.
3.With special molding process, lining material is lined on the inner wall of valve shell to resist corrosion of strong acid and strong base medium. The lining spherical and PTFE seat assembly is well sealed, achieves zero leakage, and is widely used in vacuum systems.
4.The connecting part between the valve body and the cover, the middle cover and the connecting part of the valve body are in contact with the iron body, and the utility model ensures that the valve has no displacement and zero leakage between the parts in using. And can bear that medium rapid evacuation, resulting in the moment of negative pressure.
5.The ball and the valve stem are integrated, eliminating the rotating angle difference, and preventing the risk of the stem from being out of the body due to the pressure change, thereby ensuring the safety and reliability of using.
6.Ball valve structure is simple, easy maintenance, valve seat (sealing ring) is active,disassembly and replacement are more convenient.
7.Using combination of PTFE “V” filler and fluorine rubber “V” packing, to ensure that zero leakage of the valve stem sealing.
