1Q941H 16C DN80 electric flange cast steel ball valve for oil productsProduct Introduction
Partial rotary ball valves can be fully closed and opened by rotating 90 °. Compared with gate valves and globe valves of the same specifications, ball valves are smaller in size, lighter in weight, more powerful in function, more reliable, and easier to install in pipelines. Excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, and long service life. The valve body channel and connecting pipe diameter are equal and form one diameter, allowing the medium to flow through almost without any loss. The product is usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid, and vapor media, it is also suitable for controlling sewage and media containing fibrous impurities. It has wide applications in fields such as petrochemicals and long-distance pipelines. Its closure is a partially spherical part with holes, which rotates with the valve stem to open or close the valve. The flow direction can be arbitrary, the adjustable range is wide, and it can be used in high-pressure and large-diameter applications to control high viscosity media with fibers and fine particles.

IIQ941H 16C DN80 electric flange cast steel ball valve for oil productsProduct advantages:
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, plastic is widely used as the sealing surface material for electric ball valves, with good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.
5. Easy to maintain, the electric ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.
6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
7. Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications from high vacuum to high pressure.
Main functions:
1. The electric actuator is used in conjunction with valves to achieve intelligent control and network control of the actuator,
2. The product is equipped with a LCD screen, which allows for on-site viewing of the status and setting parameters of the actuator,
3. Aluminum alloy shell can shield external electromagnetic interference and improve product reliability,

four、Q941H 16C DN80 electric flange cast steel ball valve for oil productsDaily use and maintenance:
In order to drive away moisture and prevent condensation, electric actuators can be equipped with electric heating elements inside the host box. Outdoor actuators or environments that are too humid should generally be equipped with electric heating elements.
But some users do not pay enough attention to this, and there are occasional occurrences of circuit short circuits or mold growth caused by condensation. Therefore, we strongly recommend installing actuators outdoors, or even if they are installed indoors, if the local climate is humid, they must be equipped with electric heating elements. Of course, in some applications where the ambient temperature is too high, electric heating elements cannot be used, such as the secondary air system in power plants. In this case, adding electric heating elements would be counterproductive and cause unnecessary trouble.
Similarly, in order to prevent moisture, actuators (with electric heating elements) should also be powered on when stored in humid environments for a long time to ensure that the circuit board does not mold. If the above requirements are not followed, or if the actuator is not equipped with an electric heating element, the actuator main box and control box must be opened for inspection after installation and before powering on. If condensation or circuit mold is found, it must be dried and repaired before powering on for testing, otherwise it will cause damage to the actuator.
