Worm gear eccentric ball valves are categorized by application into six major series: general-purpose valves, pipeline valves, slurry-specific valves, gas-specific valves, petrochemical-specific valves, and pulverized coal injection-specific valves. They are available in manual, 空気圧, and electric operation, with eight pressure ratings (PN0.25～10.0Mpa) and hundreds of specifications (40～1000). These valves are a replacement for gate valves, グローブバルブ, Y-type valves, and ball valves in the petroleum, 化学薬品, 冶金学的な, 力, and gas industries. Currently, they are widely used in pulverized coal injection in the steel industry, slurry, mother liquor, and alumina powder conveying in the alumina industry, 油圧 (or dry) ash removal in the power industry, and in the petrochemical and gas industries.

Worm Gear Eccentric Ball Valve, Top-Entry Eccentric Ball Valve Applications:
Petrochemical Industry Special: Designed for high-pressure, high-temperature media in the petrochemical industry, filled with flammable, 爆発物, and easily corrosive media such as weak acids and alkalis. Features include excellent sealing, 耐食性, easy opening and closing, and automatic removal of scale from the valve surface. Suitable for transporting crude oil, heavy oil, およびその他のメディア, as well as in petroleum cracking, food processing, and other processes. (石油, 天然ガス, 石炭ガス, 水, 等)
Blast Furnace Gas and Gas Special: The sealing pair is made of Cr-Mn-Si hard alloy, which is fire-resistant, 防爆, and anti-static. The sealing pair can withstand high temperatures up to 560℃. Its corrosion resistance and anti-galling ability are more than 6 times that of stainless steel sealing pairs. It is particularly suitable for use in pipeline transportation and pressurization stations for coal gas, coke oven gas, water gas, 液化ガス, そして天然ガス. (Blast furnace gas, 天然ガス, dust-laden gas, 等) For slurry mixed fluids: The ideal process valve for conveying two-phase mixed fluid media such as easily precipitated, scaled, or crystallized slurries, slurry ash, 等. It can overcome scale obstacles to achieve smooth closure. It features a novel structure and unique design, offering advantages such as high efficiency and energy saving, good wear resistance, 確実なシール, 簡単な操作, 素早い開閉, そして長寿命. (Conveying process slurries, slurry ash, 等. containing particulate matter) For pipelines: A straight-through hemispherical valve with no reduction in diameter. The valve body channel connects to the pipeline in a straight line with the same cross-sectional area, resulting in less resistance than a reduced diameter valve. Full opening and full closing can be achieved with just a 90-degree rotation, facilitating long-distance pipeline transportation control. (Pulverized coal injection and gas transportation)
The worm gear eccentric hemispherical valve, specifically the top-mounted eccentric hemispherical valve, offers the following advantages:
1. Compact side-mounted structure and lightweight, suitable for applications requiring limited installation space.
2. 低い流体抵抗; its resistance coefficient is equal to that of a pipe section of the same length.
3. シンプルな構造, 小型, そして軽量.
4. Cutting function; it can cut off impurities (twigs, textile bags, 等) in the medium when closed.
5. しっかりしていて信頼性が高い; the sealing surface material of the ball valve widely uses plastics, providing excellent sealing performance, and it is also widely used in vacuum systems.
6. Convenient operation; 素早い開閉; only a 90° rotation is needed from fully open to fully closed, リモートコントロールを容易にする.
7. メンテナンスが容易; the ball valve has a simple structure, シールリングは通常可動式です, 分解と交換が便利になります.
8. 全開時または全閉時, ボールとシートのシール面は媒体から隔離されています, 媒体流時のバルブシール面の浸食を防止.
9. 幅広い用途があります, with pipe diameters ranging from a few millimeters to several meters, and can be used in applications ranging from high vacuum to high pressure. When the sphere rotates 90 度, the entire inlet and outlet should present a spherical surface, thereby cutting off the flow.
