FlowBiz makes a Single-Piece Design Ball Valve that has the advantage of economical cost and stalwart. The body is in a single piece & a smaller ball has to be used, leading to a reduced port known as the reduced bore. Results in reduced flow through the valve, as the ball bore is one size smaller than the pipe size. The single-piece designed ball valve has a body & end connection formed from a single piece of material. The valve trim and seals are inserted through one of the end connections. This type of valve will not have a port size equal to the line size. The benefit is that the valve will be cost-effective and solid. Single-Piece Design Ball Valve is preferred in case of hazardous and toxic liquids or chemicals.
