Ball Valve Malaysia is a quarter rotary motion valve that uses a spherical disk to stop or start the flow of liquid or gas. When the valve is opened, the ball rotates to the point where the hole through the ball aligns with the valve body inlet and outlet. When the valve is closed, the ball is rotated so that the orifice is perpendicular to the flow opening of the valve body and flow is stopped.
Ball valves are known for their long service life and provide reliable sealing throughout their life, even when the valve has not been used for a long time. As a result, they are more popular as shut-off valves than gate valves. In addition, this valve is more resistant to contaminated media than most other types of valves. In a special version, the ball valve is also used as a control valve. This application is less common due to the relatively limited accuracy of flow rate control compared to other types of control valves. However, ball valves also offer some advantages here. For example, the valve still ensures reliable sealing, even in the case of dirty media or wastewater.
The Ball Valve Malaysia is supported and sealed by the ball valve seat (5) and O-ring (2) around the valve stem. Everything is in the valve housing (3). The ball has a hole running through it, as seen in the cross-sectional view in the figure. When the valve stem is turned a quarter turn, the orifice opens to the flow allowing the medium to flow through or is closed to prevent the flow of the media
Full bore valve is a type of ball valve with the diameter of the ball bore equal to the diameter of the connecting pipe. These types of ball valves are commonly used in blowdown, piggable lines, production manifolds and pipelines.
Reduced bore valves are a type of ball valve whose ball hole diameter is not the same size / smaller than the size of the connecting pipe. The minimum diameter of the ball valve is one size smaller than the diameter of the connecting pipe, for example; the diameter of the pipe is 4 inches, the diameter of the ball valve is 3 inches.
Ball valves are often used in hydrocarbon processes because they are able to regulate the flow of gas and steam, especially for low pressures. This valve can be quickly closed and is tight enough to hold liquids. Ball valves in general do not use a handwheel, but only use a stem handle. To open or close the ball valve it only takes a quarter turn or an angle of 90°. The simple design minimizes the pressure drop when the valve is fully opened.
Ball Valves are widely used and functioned on:
