Use of copper ball valves

Copper ball valve: evolved from the plug valve, its opening and closing member is a ball, using the ball to rotate 90° around the axis of the valve stem to achieve the purpose of opening and closing. The valve with pipe thread connection is connected to the pipe thread at the end of the pipe, where the inner thread can be either cylindrical pipe thread or conical pipe thread, while the outer thread must be conical pipe thread. To extend the service life of the valve, gate and ball valves should be used for full opening and full closing. It is not appropriate to partially open to do throttling use. Because part of the opening, rolling the media will erode the gate and ball sealing surface, when the medium has impurities, this erosion will be greater.
