Introduction to three-piece threaded ball valve:

Shanghai Bengao Valve produces [three-piece internal thread ball valve]. Its closing part is a sphere. The sphere rotates around the center line of the valve body to achieve opening and closing. [Three-piece internal thread ball valve] is mainly used in pipelines to cut off distribution and change the flow direction of the medium. [Three-piece internal thread ball valve] A new type of valve that has been widely used in recent years. It has some advantages unique to its own structure, such as no friction in the switch, the seal is not easy to wear, and the opening and closing torque is small. This allows the size of the actuator to be used reduced. Equipped with electric actuators and pneumatic actuators, the medium can be adjusted and tightly cut off.
The three-piece internal thread ball valve relies on a rotating valve to open or block the valve. Ball valves are light on and off, small in size, can be made into large diameters, have reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are always in a closed state and are not easily eroded by the medium. They are widely used in various industries.
According to the sealing structure principle of ball valves, ball valves are divided into floating ball valves and fixed ball valves. Floating ball valves mainly rely on fluid pressure to press the ball on the valve seat at the outlet end to form a floating seal, so the pressure and caliber used are limited. The ball of the fixed ball valve is supported by the upper and lower bearings installed on the valve body. The position of the ball is fixed. The sealing effect is achieved by pressing the valve seat to the ball by the spring and fluid pressure. Therefore, the opening and closing torque is higher than that of the floating ball valve. Much smaller, suitable for high pressure and large diameter applications. Three-way ball valves and four-way ball valves are used for fluid reversal pipelines, with types and types
