In the process of industrial automation, precise and efficient fluid control is of vital importance, and the electric
V-Type Ball Valve serves as a key device to meet this demand. It perfectly integrates the precise control of electric actuators with the unique structural advantages of V-type ball valves, playing an irreplaceable role in numerous industrial fields.
The electric V-type
ball valve is primarily composed of a valve body, V-type ball core, electric actuator, sealing components, and valve stem:
- The valve body is commonly made of stainless steel, carbon steel, or special alloys to withstand the pressure of the medium in the pipeline.
- The V-type ball core, as the core component, features a special V-notch design, which is crucial for achieving precise flow regulation.
- The electric actuator receives standard control signals such as 4-20mA or 0-10V, converting electrical energy into mechanical energy to drive the valve stem rotation, thereby moving the V-type ball core within the valve body. As the rotation angle of the ball core changes, the flow area formed between the V-notch and the valve seat adjusts accordingly, enabling fine-grained control of the medium flow. In the closed state, the ball fits tightly with the valve seat, ensuring tight sealing via the sealing components to prevent medium leakage.
The electric V-type ball valve stands out with its remarkable performance:
- High Regulation Accuracy: The V-notch endows the valve with an approximately equal percentage or linear flow characteristic, and some high-quality products achieve a regulation accuracy of ±0.5%, precisely meeting the strict requirements of various complex processes for flow control.
- Strong Shearing Ability: When facing media containing fibers, particles, and other impurities, the V-type ball core demonstrates powerful shearing capacity. During valve opening or closing, the strong shearing force between the V-notch and the valve seat easily cuts off fibrous impurities, effectively preventing blockages and ensuring long-term stable operation. This feature makes it excel in industries such as paper making and wastewater treatment.
- Superior Sealing Performance: Whether using soft seals (such as PTFE) or metal seals, the electric V-type ball valve often reaches the ANSI Class VI leakage standard, guaranteeing the safety and stability of medium transportation.
- Wide Regulation Range & Low Flow Resistance: With a regulation ratio typically exceeding 100:1 (far higher than ordinary valves), it enables precise control under large flow variation conditions. In the fully open state, its flow path is almost identical to the pipeline inner diameter, resulting in extremely low flow resistance and minimal pressure loss, greatly improving fluid transportation efficiency.
- Chemical Industry: Used for flow regulation of corrosive media like acids and alkalis, as well as feed control for reaction kettles. Its corrosion-resistant valve body materials and reliable sealing performance ensure safe and stable production processes.
- Petroleum & Natural Gas: In crude oil transportation pipelines and natural gas distribution systems, it precisely adjusts according to changes in parameters such as pressure and flow, ensuring efficient and safe energy transportation.
- Power Industry: In links such as boiler feedwater and condensate water treatment, its precise flow control helps maintain stable operation of power generation equipment and improves energy conversion efficiency.
- Water Treatment: Whether regulating sludge flow in wastewater treatment plants or precisely controlling dosing systems, it adapts to complex medium environments with its own advantages, ensuring the smooth progress of water treatment processes.
- Paper Making Industry: Pulp flow control significantly impacts paper quality. The shearing function of the electric V-type ball valve effectively handles fibers in pulp, avoiding valve cavity blockages and ensuring stable pulp transportation and flow regulation.
- Food & Pharmaceutical Industry: Facing strict hygienic process control requirements, it can adopt FDA-certified sealing materials to meet the needs of pollution-free and precise medium control.
