The electric three-piece ball valve (electric internal thread ball valve) is assembled from three parts: the left and right valve casings and the middle valve body. Four longer bolts traverse the three-section valve casing, and tightly clamp the middle valve body from both ends. The biggest advantage of the electric three-piece ball valve is that it is particularly easy to disassemble. When the valve fails or needs to be repaired, it is not necessary to disassemble the thread of the pipeline, but the four-piece ball valve can be taken off directly, and the body part can be taken out. It not only reduces the probability of failure, but also improves the working efficiency. It is especially suitable for working conditions with small mechanical volume and narrow space.
Electric three-piece ball valve principle:
The three-piece electric ball valve has reliable sealing performance and high pressure. Its action principle is to drive the valve core to rotate 90 degrees through the power supply voltage of the electric actuator to open and cut off the medium. It can be designed as The two-position switch control of the medium can also realize the proportional adjustment of the medium flow, pressure, temperature and other parameters in the pipeline.
Electric three-piece ball valve standard specification:
Test inspection: API598, EN12266
Threaded end: ASME B1.20, BS21 DIN2999/259, BSP ISO7/1, ISO228/1 JIS B 0203
Butt weld ends: ASME B16025
Sleeve Welding Ends: ASME B16.11
Flange connection: ASME B16.5 DIN2542~2545 JIS B2238
Classification and difference of electric chip ball valve:
The movable one-piece ball valve is one-piece, and the ball is fixed by a plug, which facilitates its maintenance and can be used in working conditions that require quick opening and quick closing.
The electric two-piece ball valve is composed of two parts, which are fixed by two pieces of valve bodies clamping the ball. The maintenance is relatively complicated. The tightness of the middle screw is related to whether there will be air leakage,
The electric three-piece ball valve is similar to the two-piece ball valve. It consists of left and right end covers and a middle valve body, and then enters the sheep clamp with necks on both sides. Its pressure is higher than that of the other two types.

We offer a wide plethora of Zinc in many forms including LME registered
and non registered Special High Grade Ingots and Jumbos, cathodes,
dust, foil, granules, powder, pieces, anodize activated powder, shot,
and a mossy form.
Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is
malleable at 100 to 150°C. It is a reasonable conductor of electricity, and burns in air
at high red heat with evolution of white clouds of the oxide. Plating thin layers of zinc
on to iron or steel is known as galvanizing and helps to protect the iron from corrosion.
The material is loose steel scrap processed through an incinerating plant for domestic waste followed by magnetic separation, fragmentized into pieces and consisting partly of tin coated steel cans.
At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form.
The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues.
The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process.
Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed.
The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise.
The collected stock, is stored in open air, on cemented flooring.
Due to the scrap dimensions and the material conditions, this particular scrap, should be carefully evaluated first, by the end users, to confirm its adequate recovery ratio and its suitability to be re-melted in the electric arc furnace.
