1. Core functions
Medium opening and closing and flow control
The electric ball valve drives the ball to rotate 90° through the electric actuator, quickly realizing full opening or full closing of the pipeline medium, which is suitable for remote cutoff or conduction control of liquids, gases and steam. Its low flow resistance design can reduce fluid pressure loss and improve transportation efficiency.
Industrial automation integration
As the core execution unit of the automation control system, the electric ball valve can be linked with DCS, PLC and other systems, respond to control signals in real time, and realize precise adjustment of chemical production, energy allocation and other scenarios. Some models support opening adjustment function to meet the dynamic control requirements of flow and pressure.
Adaptation to complex environments
The electric ball valve with PTFE seal or forged valve body design can adapt to harsh working conditions such as high pressure (such as Class900), high temperature (≤300℃) or particle-containing media (such as catalyst slurry), ensuring long-term sealing stability.
2. Typical application scenarios
Petrochemical industry
Control the transportation and storage of crude oil, liquefied gas, and acid and alkali solutions, and support remote operation in explosion-proof environments;
Used for raw material feeding, pipeline switching and emergency cutting of reactors to improve production safety and efficiency.
Power and energy system
Boiler steam pipeline regulation of thermal power plants, flow control of cooling water systems in nuclear power plants;
Media isolation and pressure management in new energy fields (such as hydrogen energy storage and transportation, LNG facilities).
Water treatment and municipal engineering
Large-diameter (DN1200) water flow opening and closing of urban water supply networks, and control of sediment-containing media in sewage treatment plants;
Corrosion-resistant valve selection for seawater desalination systems, adapted to high-salinity environments.
Food, pharmaceuticals and building facilities
Sanitary control of aseptic filling lines and clean room pipelines, in compliance with GMP standards;
Automated flow regulation of hot and cold water circulation in air-conditioning systems and fire-fighting pipelines.
3. Technical advantages
Fast response: Electric drive realizes millisecond-level switching action, which is suitable for high-frequency operation scenarios; Reliable sealing: The leakage level of soft sealing structure (such as EPDM, NBR) reaches VI level, and the hard seal can withstand the erosion of granular media; Convenient maintenance: Modular design supports online replacement of seals to reduce downtime costs.
Electric ball valves have become key equipment for modern industrial fluid control due to their high degree of automation, strong environmental adaptability and universality in multiple industries. The selection needs to comprehensively consider the medium characteristics, pressure level and control accuracy requirements.
