1、 The application scope of internal thread pneumatic ball valve The internal thread pneumatic ball valve and butt welding pneumatic ball valve are applicable to various pipelines with PN1.0~4.0MPa, operating temperature of - 29~180 ℃ (the sealing ring is reinforced polytetrafluoroethylene) or - 29~300 ℃ (the sealing ring is aligned polystyrene), and are used to cut off or connect the medium in the pipeline. Different materials can be used for water, steam, oil, nitric acid, acetic acid and other media.

The main advantages of non-metallic flexible compensator are:
1. Noise elimination and vibration reduction: it can effectively reduce the noise and vibration of boiler, fan and other systems, and save a lot of manpower
2. Good high temperature resistance and corrosion resistance: the selected fluoroplastics and organosilicon materials have good high temperature resistance and corrosion resistance.
3. Good sealing performance: there is a relatively complete consumer assembly system, and the fiber compensator can ensure no leakage.
