Product Description
Durable stainless steel NPT BSP ss 304 316 valve threaded ends full bore Ball Valve manual 3 piece floating Valve ball
Funcation description:
A ball valve is a form of quarter-turn valve that 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.
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.

1. The fluid resistance is small; its resistance coefficient is a section of equal length.
2. Simple structure, small volume, light weight
3. Compact and reliable; the gate valve sealing surface is made of widely used plastic; the sealing is good; and it has been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from open to close, just rotate 90°; this is advantageous for the remote
control.
5. Easy maintenance structure is simple; sealing ring, which generally remove replacements, is more convenient
6. In the fully open or fully closed state, the valve body and seat sealing surface and the dielectric isolation, medium-through, do not cause the valve sealing surface erosion.
7. The applicable scope is wide, ranging from small to several millimeters to large to a few meters. From high vacuum to high pressure, the ball can rotate 90 degrees, and the inlet and outlet should be completely spherical, thereby cutting flow.
