A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It 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 perpendicular to it when closed, making for easy visual confirmation of the valve's status.
Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves. With this being said, they do lack fine control in throttling applications.
The ball valve's ease of operation, repair, and versatility lend it to extensive industrial use, supporting pressures up to 1,000 bar (15,000 psi) and temperatures up to 752 °F (400 °C), depending on design and materials used. Sizes typically range from 1/4" to 48". Ball valves are constructed of and not limited to metal, plastic, or special materials such as duplex, hastelloy and monel.
We stock a wide range of ball valves from 2-Piece & 3-Piece (Screwed End, Socket Weld End & Butt Weld End) to Flanged ANSI & PN in a range of specifications in relation to the above detail.
