WCB Carbon Steel 304 316 316L Pneumatic O-type Shut-off Ball Valve Switch Ball Valve
Electric actuator is used for controlling valves of 0°-270° rotation and other similar products, such as butterfly valve, ball valve, damper, flapper valves, plug valves, louver valve and so on.
It is widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, light industry and other industries. It can be driven by 380V/220V/110V AC power or 24V/110V DC power. Control signal can be 4-20mA current signal or 0-10V voltage signal.
It can move the valve to desired position, and achieves automatic control. The maximum output torque is up to 2000N·m. (CE certificate approved)
| Pneumatic ball valve is used to cut off or connect the medium in pipeline, suitable for two cutting or adjusting occasions.Can be used for water, steam, oil, nitric acid, acetic acid, oxidation medium, urea and other media.Widely used in paper making, petroleum, chemical industry, metallurgy, electric power, water treatment, environmental protection, petroleum, light industry and other industries in automatic control. | |
