Common types of electric actuators include multi-turn, quarter-turn, intelligent, part-turn (rotary), linear, explosion-proof, and compact models. Ball valves primarily include floating, trunnion-mounted, O-port, V-port, and three-way configurations. Combining these actuators with ball valves results in a diverse range of products.
Control boxes can be added to enable remote operation, and additional accessories can expand functionality-such as electric positioners for flow regulation, resistance or current valve position transmitters for monitoring and controlling opening degrees, and manual override handwheels for operation during power outages. Other common accessories include insulation jackets and explosion-proof limit switches. Initial selection should be based on specific operating conditions.
Electric ball valves are widely used in industries such as oil and gas, pharmaceuticals, food processing, hydropower, nuclear power, general power generation, water supply and drainage, district heating, and metallurgy. They are suitable for applications involving throttling, shut-off, isolation, on/off control, and flow regulation. These valves are characterized by their versatility, compact size, reliable sealing, high flow capacity, and remote control capabilities, while also offering advantages such as pressure, temperature, and corrosion resistance, low flow resistance, and a long service life.
