Stainless steel ball valve working principle of the stainless steel ball valve just has to rotate 90 degrees of operating and small rotational torque can be closed tight. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Ball valve itself is the main characteristics of compact structure, easy operation and maintenance, stainless steel ball valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. Ball valve body can be a whole, also can be combined. This valve shall generally be installed in the pipeline. Stainless steel ball valve categories: stainless steel pneumatic ball Industrial Valves, stainless steel electric ball valves, stainless steel ball valve manually. Stainless steel ball valve material is divided into 304316321 stainless steel ball valve. The working principle of ball valve is to rely on rotary valve core to keep the valve open or closed. Ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Ball valve and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve. Stainless steel ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Ball valve is widely used a new type of valve. 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, simple structure of ball valve, 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. Ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life. Ball valve and ball valve has a O V type ball valve. O-type ball valve structure of floating type, ball core for precision casting, hard chromium plating processing, appearance with enhanced ptfe seat material, flow crossing the same as the pipe diameter, flow capacity, little flow resistance, closing without leakage, generally do switch Industrial Valves is used, especially suitable for high viscosity, fiber, granular media; V-shaped ball valve USES the fixed structure, the ball on a v-shaped incision, which can realize proportional control, flow characteristic is approximate equal percentage. Process equipment under different choice of pneumatic or electric, forming an and electric ball valves, pneumatic ball valve such as pneumatic ball valve must be regulated to achieve proportional valve positioner, such as the electric ball valve to be regulated to achieve proportional election electronic actuators or servo amplifier, etc. From the material, can be divided into: carbon steel ball valve, 304 stainless steel ball valve, copper ball valve and ball valve with 316 applications, can be divided into: high pressure ball valve and the low pressure ball valve ball: mainly used in oil, gas, hydraulic oil, engineering machinery industry such as low pressure ball valve: mainly used in medium for water and other noncorrosive pipe on the road!
