Pneumatic steam ball valve is one of the most widely used industrial control instruments, mainly composed of pneumatic actuators and various types of common valves. Compared with electric valves, the actuator is different. Although it is relatively convenient to use without electric valves, it is more suitable in many situations than electric valves. And according to the price of pneumatic actuator ball valve suppliers, the price of pneumatic ball valve suppliers is cheaper than that of electric valve.
Which working conditions should pneumatic valves be used?
Here are some suggestions from pneumatic ball valve manufacturers.
Compared with electric valves, pneumatic ball valves are more suitable for explosion-proof applications. The main reason is that the driving source of pneumatic ball valve is air source. There are no electronic components in the pneumatic actuator. When used in flammable and explosive occasions, even if there is a fault, it will not be as easy to generate sparks as the electric valve. So it will not bring about potential safety hazards. According to these working conditions, explosion-proof electric valves have been produced. However, from the point of view of price and performance, if there is air source on the working site, the pneumatic valve should be selected for use. Corrosion-resistant pneumatic valves should also be chosen when you are transporting toxic and dangerous media, because pneumatic ball valves have the function of fault reset. Customers choose switch pneumatic valves when ordering. In case of failure or gas source breakdown, pneumatic ball valves can automatically restore full shutdown or full open state according to user’s needs to protect the safety of working conditions. This is not available in general electric valves.
