Ball valves have superiority. 1, with the lowest flow resistance (real 0); 2, body symmetry, in particular welded body structure, can well withstand the stress from the pipe; 3, in the larger range o

When the valve is in the open position the hole in the ball is lined up with the opening in the copper pipes on either side of it. When the ball valve is in the closed position the holes disappear fro

Most ball valves are of the quick-acting type (requiring only a 90-degree turn to operate the valve either completely open or closed), but many are planetary gear operated.

The fix ball valve is distinct from that of floating ball valve. When it functions, the whole electrical power developed by the fluid pressure on the ball will entirely pass to the bearing, which trig

When the ball valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you “see” the valve’s posit

Full port: This has an over sized ball so that the hole in the ball is of the same size as the pipeline thereby resulting in lower friction loss. The valve is larger and the flow is unrestricted.

Lined ball valves rely on elastomers (rubber) and/or polymers (PTFE) to totally isolate the valve body and stem journal area from the corrosive and/or erosive effects of the line media.

there are several method styles which consists of individual body, split body, three product body, best entry and welded body. The big difference amid the ball valves is centered upon the casing, whic
