BALL VALVE

Manufacturing note

A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn around its axis, the medium can flow through or is blocked. Ball valves are manufactured in one-piece, top entry, two-piece and three-piece bodies. A top entry body allows access to the ball and seats for maintenance without the need to remove the valve and is preferred for larger sizes. They can be characterized by a long service life and provide a reliable sealing over the life span, even when the valve is not in use for a long time. Nascent fittings being one of the leading Ball Valve Manufacturer in India, manufactures Ball Valves with Full Port or Regular Port constructions. Where pressure drop is required, the user is advised to choose full port construction. When a Ball Valve is chosen to replace a Gate Valve, a Full Port Ball Valve is the obvious choice. As a result, they are more popular as a shut off valve then for example the gate valve. Ball valves are more resistant against contaminated media than most other types of valves. Ball valves are straight-through flow valves that give positive shutoff with the least amount of pressure drop and turbulence in the flow. The flow barrier is a ball that has been rotated 90 degrees in the direction of the flow. Ball valves are robust and typically provide a perfect shutoff.
