The three-piece ball valve is one of the most widely used valves in recent years. The three-piece internally threaded ball valve is a new type of ball valve. It has some unique advantages of its own structure. For example, the switch has no friction, and the seal is not easy to wear. The opening and closing torque is small. In this way, the specifications of the equipped actuator can be reduced, and the multi-turn electric execution structure can be used to achieve the adjustment and strict shut-off of the medium.
The three-piece internally threaded ball valve is suitable for working conditions requiring strict shut-off in petroleum, chemical, urban water supply and drainage, etc. The internal thread ball valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, easy maintenance, the sealing surface and the spherical surface are often closed, not easy to be eroded by the medium, and are widely used in various industries.
The three-piece internally threaded ball valve can be closed tightly with a 90 ° rotating operation and a small turning torque. The completely equal valve body cavity provides little resistance to the medium and a straight flow path. In fact, the ball valve body can be a whole , Can also be combined.
