3D Animation of Valve---Valve Manufacturer China
Fixed ball valve, the sphere by a rotary valve to control the opening and closing of the valve. The sphere in the middle there is a hole, can rotate 90 °, the diameter of the hole is equal to or less than the diameter of pipe. When the ball rotated 90 °, import and export of pipeline surface is spherical, and close the valve to cut fluid. When the ball valve turn 90 °, the pipe surface are the ball hole surface of imports and exports, the fluid through valves, ball valves can rotate to a different point of view, which can control the size of the fluid. Fixed ball valve commonly used in general line, such as conveying water, oil, steam, etc.

What happens when the control valve fails?
The key inspection position of the regulating valve in case of failure:
1. The inner wall of the valve body, for the use of pressure difference and corrosive medium occasions of the regulator, the inner wall of the valve body is often affected by the medium and corrosion, must focus on the inspection of pressure, corrosion resistance.
2. Valve seat and control valve should be noted during inspection, because of medium infiltration, the threaded inner surface of the fixed valve seat is easy to be corroded and the valve seat is loose. For the valve working under high pressure difference, should also check whether the sealing surface of the seat seat is flushed.
3. The valve core, the valve core is the movable part of the work of the control valve, erosion by the medium, the most serious corrosion, maintenance to carefully check whether the parts of the valve core are corroded, wear, especially under the condition of high pressure difference valve.
