Insulated ball valve is a type of valve that is generally installed horizontally and belongs to the same type as flange gate valve. The closing element is a sphere, which rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium.

Insulated ball valves have good insulation and cooling characteristics, and the valve diameter is consistent with the pipe diameter, while effectively reducing the heat loss of the medium in the pipeline. Mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, and food, to transport high viscosity media that will solidify at room temperature.
Insulated ball valve and flange gate valve belong to the same type of valve, with the difference being that their closing part is a sphere, which rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. Two piece ball valve and three piece ball valve are a new type of valve widely used in recent years, which are generally installed horizontally.
Advantages of insulated ball valves:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable. Currently, plastic is widely used as the sealing surface material for ball valves with good sealing performance, and it has also been widely used in vacuum systems.
4. Easy to operate, quick to open and close, with only a 90 ° rotation from full open to full close, facilitating remote control.
5. Easy to maintain, the ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement more convenient.
6.When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at both the inlet and outlet to cut off the flow.
Insulated ball valve is a relatively new type of ball valve, which has some unique advantages of its own structure, such as frictionless switch, less prone to sealing wear, and small opening and closing torque. This can reduce the specifications of the equipped actuator. Equipped with a multi turn electric actuator, it can achieve adjustment and tight cutting of the medium.
Closing process:
When the valve is closed, rotate the handwheel clockwise, and the valve stem begins to descend, causing the ball to leave the valve seat and start rotating.
Continuing to rotate the handwheel, the valve stem is subjected to the action of a guide pin embedded in its spiral groove, causing both the valve stem and the ball to rotate 90 degrees simultaneously.
When 3 was about to close, the ball had already rotated 90 ° without contact with the valve seat.
During the last few turns of the handwheel, the angular plane at the bottom of the valve stem mechanically wedges against the pressure ball, tightly pressing it against the valve seat to achieve complete sealing.
