The three-piece ball valve and the gate valve are the same type of valve. The difference is that the closing part is a sphere. The sphere rotates around the center line of the valve body to open and close the valve. Ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Three-piece ball valve is a new type of valve widely used in recent years. The working principle of the ball valve is to make the valve open or closed by rotating the valve. Internally threaded ball valve switches are lightweight, small in size, can be made into large calibers, reliable in sealing, simple in structure, and easy to maintain. Sealing surfaces and spherical surfaces are often in a closed state, which is not easily eroded by media, and has been widely used in various industries.
The ball valve and the plug valve are the same type of valve. Only the closing part is a ball. The ball rotates around the center line of the valve body to open and close the valve.

Ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Ball valve is a new type of valve widely used in recent years.
The three-piece internally threaded ball valve can be closed tightly with only 90 degrees of rotation and a small torque. The completely equal valve body cavity provides a low resistance, straight flow channel for the medium. Generally speaking, ball valves are most suitable for direct opening and closing, but recent developments have designed ball valves to make them throttle and control flow. The main features of the ball valve are its compact structure, easy operation and maintenance, suitable for general working media such as water, solvents, acids and natural gas, but also for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integrated or combined.
The three-piece internal thread ball valve is a relatively new type of ball valve, which has some unique advantages of its own structure, such as no friction on the switch, difficult to wear the seal, and small opening and closing torque. This reduces the size of the actuators. Equipped with a multi-turn electric actuator, it can realize the regulation and strict shut-off of the medium. It is widely used in petroleum, chemical industry, urban water supply and drainage and other conditions that require strict cutoff.
