Function Description:
2PC Thread Ball Valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating 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.
2PC Thread 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 applications, where they are often preferred to gate and globe valves, but they lack their fine control in throttling applications.
Its stainless steel 201&304&3016 is perfect for various water,oil and gas applications, The two-pieces full port design allows for unimpeded flow,minimal pressure drop and less fluid separation.

Ball valve Application
Ball valve, opening and closing parts (ball) driven by the valve stem, and around the ball valve axis for rotary movement of the valve. Can be used for fluid regulation and control, 2PC Thread Ball Valves are generally installed horizontally in the pipeline
Ball valves classification
By structure:
Floating ball valve, fixed ball valve, V-ball valve, three-way ball valve, manual ball valve, pneumatic ball valve, electric ball valve, welding ball valve and so on.
Ball valve characteristics
①Low fluid resistance and small volume.
②Tight and reliable, good seal.
③Convenient operation, quick opening and closing.
④Simple structure, convenient maintenance.
⑤ Wide range of application, high vacuum or high pressure can be applied.
