Introduction to the introduction of pneumatic three-way ball valve

Definition of pneumatic three-way ball valve
 Pneumatic three-way ball valves typically use rubber, nylon and Teflon as the seat seal material. The corresponding temperature is subject to the limitations of the seat seal material. The application principle of the pneumatic three-way ball valve is that its cut-off function is achieved by the metal ball being pressed against the plastic valve seat under the action of the medium (floating ball valve). The valve seat seal is deformed by elastic deformation in a local area under a certain contact pressure. This deformation can compensate for the manufacturing precision and surface roughness of the sphere and ensure the sealing performance of the ball valve.
Safety pin knowledge of pneumatic three-way ball valve
In view of the fact that the pneumatic three-way ball valve is made of plastic material, the performance of the ball valve should be considered in terms of fire resistance and fire resistance. Especially in the petroleum, chemical, metallurgical and other use sites, the use of ball valves in flammable, explosive media equipment and piping systems, should pay attention to fire and fire. In case of excessive temperature, dangerous events such as blasting occur.
Pneumatic three-way ball valve for occasions
Pneumatic three-way ball valves are also suitable for use in light piping, low pressure cut-off (small differential pressure), corrosive media piping systems. Ball valves are also available in low temperature (deep cold) units and piping systems. In the oxygen pipeline system of the metallurgical industry, it is urgent to use a ball valve that has been strictly degreased. A full-diameter welded ball valve is not required when the main line in the oil pipeline and the gas pipeline is to be buried underground. It is not necessary to use a ball valve with a special structure with a V-shaped opening when it is required to have adjustment performance. In petroleum, petrochemical, chemical, electric power, and urban construction, metal-to-metal sealed ball valves are available for piping systems with operating temperatures above 200 degrees.
