Pneumatic ball valve selection method is introduced

the working principle of the pneumatic ball valve is rotating pneumatic ball valve open or closed. Pneumatic ball valve switch is lightweight, small size, pneumatic valve can make a big caliber, reliable sealing, simple structure, convenient maintenance, regularly check the sealing surface and spherical in the closed state, medium susceptible to erosion, get a lot of applications in various industries.
ball is roughly divided into two categories, floating ball, pneumatic valve, pneumatic fixed ball valve, pneumatic valve, metal hard seal ball V pneumatic valve, wafer pneumatic ball valves, heat preservation ball pneumatic valve, pneumatic valve, pipe track ball, wool top pneumatic ball valve, pigging pneumatic valve, pneumatic valve, high pressure forging tee, Four-way) Balls, line, the pneumatic ball valve, cryogenic ball pneumatic valve, pneumatic valve, corrugated pipe pneumatic valve, eccentric hemisphere all welded ball pneumatic valve, pneumatic ball valve and other special.
O type pneumatic ball valve floating structure, the core of precision casting, hard chrome plated surface appearance, seat using metal or ptfe material flow and pipeline crossing with diameter, large flow, little flow resistance, closing without leakage, generally do switch pneumatic valve, fibrous, granular media.
v-shaped ball pneumatic valve has a fixed structure, opened up a v-shaped incision ball core, proportional control can be realized.
is suitable for a wide range of pneumatic ball valves, pneumatic ball valve suitable for:
and nominal diameter from mm to mm.
PN from vacuum to MPa.
from - ℃? The ℃ temperature.
especially in petroleum, chemical industry, metallurgy and other departments, with a soft sealing pneumatic valve equipment and piping systems inflammable, explosive or medium, but should pay attention to fire prevention and fire.
normally, two position adjustment, strict sealing performance, mud, wear and tear, reducing channel, opening and closing action quickly ( Turn/open/close) , high pressure cut-off ( Pressure) , low noise, there is phenomenon of air-pocket and gasification, a small amount of leakage to the atmosphere, a small operation torque, the fluid resistance of pipeline system, the recommended pneumatic valve.
the ball also applies to light structure, low bosom, Differential pressure) Corrosive medium, the pipeline system.
at low temperature ( Low temperature) Equipment and piping systems, can also be used for the ball.
during execution need to be adjusted, need to use the special structure of the ball, v-shaped opening can customize to pneumatic valve manufacturer.
in the oil, petrochemical, chemical, electric power, city building, working temperature in ℃ above pipeline system can use metal to metal sealed ball pneumatic valve.
in the metallurgical industry, oxygen pipeline system, using defatted ball strict processing.
when the dismissal of the main line in underground oil pipeline and gas pipeline, use the full size welding pneumatic ball valve.
ball in irrigation system, mainly for the widely application of the intake manifold. Ball has simple structure, small size, fluid flow resistance is small, the drawback is turned on or off so quickly, can produce water hammer ( When a sudden change in the flow velocity in the pressure tube will rise) In the pipeline. Therefore, should not be in the main pipe pneumatic valve, when there is no water available, or the end of the branch pipe used for washing purposes, flushing drainage effect.
