Product Summary

4 inch ball valve is a kind of ball valve that is of 4 inch. Ball valve is a kind of ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked.

4 inch ball valve is great ways to quickly adjust fluid or gas flow in a line from a fraction of an inch to over a foot in diameter. Installing ball valves in the home makes it easy to shut off gas or water with a quick twist. Advantages of ball valves for 3/4" lines over more common spigot-type gate valves is the waterless ball valve can handle high pressures and remain leak-free for many years. The large diameter gate valve means larger washers. A tight metal-on-metal seat eliminates any soft rubber pieces that can deteriorate with time.

4 inch ball valve installation: first making a place for it in the line. You either have to remove an existing valve or cut into the line. Shut off the water at the meter. If removing a threaded valve, use a proper-sized pipe wrench to turn the old valve counter-clockwise. Be careful, though, not to turn so hard the tube bends instead of the valve because corrosion has frozen the valve. Using heat from a propane torch or applying a calcium and lime cleaning solution may free frozen thread. As the valve is in a line, it's attached at both ends. Screw off one side, and then rotate in the opposite direction to remove the valve. If the old valve is soldered into the line, use the propane torch to heat the solder and then slip off the valve.
