I. Product Introduction
The electric V-type ball valve is a high-performance automated flow control device integrating a precision V-type ball core, a sturdy valve body, and a reliable electric actuator. It is specifically designed to address the challenges of controlling media containing suspended solids, slurries, or viscous fluids, which are difficult for conventional ball valves to handle. The unique V-shaped notch on the ball core not only enables on/off switching but also achieves accurate throttling and flow regulation, making it widely applicable in industries such as petrochemical, mining, papermaking, sewage treatment, and power generation. The valve adopts advanced connection methods (including flange connection as the mainstream option) to ensure stable installation, tight sealing, and strong adaptability to harsh working conditions. It realizes remote or automatic control through electric signals, significantly improving the automation level and operational efficiency of the pipeline system.
II. Product Features
-
Excellent anti-clogging performance: The V-shaped notch of the ball core generates a strong shearing force when opening and closing, which can effectively cut off fibers, slags, and other impurities in the medium, preventing blockages and ensuring smooth flow of the pipeline. This feature makes it particularly suitable for media with high impurity content, such as papermaking black liquor and mining slurry.
-
Precise flow control: The flow characteristic of the V-type ball core is approximately equal percentage or linear, which can achieve precise adjustment of the medium flow within a wide range. Cooperating with a high-precision electric actuator, it can accurately respond to control signals (such as 4-20mA), ensuring the stability of the process parameters.
-
Strong sealing performance: It adopts a hard-sealing or soft-sealing structure (selectable according to working conditions). The hard-sealing type uses wear-resistant and corrosion-resistant materials (such as stellite alloy) for surfacing, while the soft-sealing type uses high-temperature and pressure-resistant sealing materials. The combination of the V-type ball core and the valve seat forms a tight sealing pair, achieving zero leakage even under high pressure and high temperature.
-
High reliability and durability: The valve body is made of high-quality materials such as carbon steel, stainless steel (304/316), or alloy steel, which have excellent corrosion resistance, wear resistance, and pressure-bearing capacity. The electric actuator is equipped with overload protection, position feedback, and other functions, ensuring stable operation and long service life even in continuous operation.
-
Convenient operation and maintenance: The modular design of the electric actuator and the valve body allows for quick disassembly and assembly, facilitating maintenance, inspection, and replacement of parts. At the same time, it supports remote control and automatic adjustment, reducing manual intervention and operational costs.
-
Wide applicability: It can be used to control various media, including water, oil, gas, steam, slurry, corrosive chemicals, and media containing impurities. It can adapt to different working conditions such as high temperature, high pressure, and strong corrosion, meeting the needs of various industrial fields.
