Ball Valve

What is a Ball Valve?
A ball valve is acts as a quarter-turn valve that uses a perforated, hollow and revolving ball to control flow through it. The ball valve is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open and is upright to it when closed, making for easy visual confirmation of the valve’s status.

What are the features of a Ball Valve?
Ball valves are generally durable, performs well after many cycles, reliable and it closes securely even after long periods of abandonment. These assets make them an excellent choice for control applications, where they are often favoured to gates and globe valves, but they dearth their fine control in throttling applications. The ball valve operation, repair and flexibility lend it to widespread industrial use, supporting temperatures up to 400°C & pressures up to 1000 bar, based on design and materials used. Valve bodies are made of plastic, metal or metal with a ceramic. Floating balls are often chrome plated for durability. One disadvantage of a ball valve is that they trap water in the centre cavity while in the closed position. In the event of a freeze, the sides can crack due to extension of ice forming. Anyhow, a ball valve should not be confused with a “ball-check valve”, a type of check valve that uses a solid ball to prevent undesired backflow.

Types of Ball Valve
There are five general body styles of ball valves, which are: single body, split body, three-piece body top entry and welded. There are four general types of ball valves, which are full port, standard port, reduced port, and v port. The variance is based on how the pieces of the valve, especially the casing that comprises the ball itself—are manufactured and assembled. The valve operation is the same in most cases. The types of Ball Valve we provide includes BVMM (Male Thread to Male Thread), BVMF (Male Thread to Female Thread), BVMH (Male Thread to Barb), BVHH (Barb to Barb), BVFH (Female Thread to Barb) and BVFF (Female Thread to Female Thread).
