A top entry ball valve consists of a housing having an interior cavity sufficiently large to receive a conventional ball and conventional seat rings through an opening in the housing. The ball of a top entry ball valve is installed from the top, and is always used in the applications of long pipes. Beside that, a top entry valve is easy to repair, because it is not necessary to dismiss the whole valve from the pipeline to get out the ball.
When a top entry ball valve uses cast steel as its material, it comes to top entry cast steel ball valve.
Cast steel, this term originally applied to crucible steel and sometimes used to describe tool steels. More specifically, in the industry of valve making, cast steel is widely used as a material. For instance, (ASTM) A216 WCB is the specification for the cast steel the valve is made of. ENP might be a foundry or pattern code. ENP is the abbreviation of Electroless Nickel Plate demonstrating the coating of ball.
