What is a pneumatic ball valve?




is a kind of pneumatic actuators, pneumatic ball valve can be accurately according to the use of pressure to quickly adjust the switch, pneumatic ball valve is a kind of fast, limit switch speed can reach zero. 05 seconds/time, so also called quick start to cut off the ball. Pneumatic ball valves are usually equipped with auxiliary devices, such as solenoid valve, air source treatment sanlian pieces, limit switch, timer, control box, etc. Several kinds of control, the use of these devices can realize long-distance in the control room can control the switch of the valve, greatly saves manpower.
categories: common kinds pneumatic ball valve with stainless steel, plastic, health level pneumatic ball valves, pneumatic ball valve steel fixed ball valve pneumatic ball valve, ventilation, etc.

use pneumatic ball valve working principle is to use the rotary valve core to open or close the valve, it switch light, small volume, also can make large caliber, reliable sealing structure is simple, and is also very convenient to maintenance and sealing surface and the spherical often in the closed state, not easy to corrosion medium, has been widely used in all walks of life. Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Compact and reliable, the ball valve sealing surface material widely used plastic, sealing good, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control. Convenient maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
　　8. Because of the power supply adopts pneumatic ball valve is a gas, general is 0. 2 - 0. 8 mpa pressure, is relatively safe. If air leakage, pneumatic ball valve relative hydraulic, electric, gas can directly discharge, no pollution to the environment, and has higher security.
　　9. Relative to manual and turbine rotating ball valves, pneumatic ball valve can be large caliber configuration, ( Manual and turbine rotating ball valve is generally under 12 caliber, pneumatic ball valve to 48 ') diameter. ）
