With the continuous acceleration of industrialization, in order to meet the needs of the times, valve products in the market are also constantly being updated and replaced. Now, the call for "environmental protection" and "safety" in the valve market is becoming increasingly high. At present, the demand for electric valves has been increasing, mainly because they are more energy-efficient and safer to use. Compared to traditional manual valves, electric valves can be used faster than ordinary valves, reducing manual labor and greatly improving work efficiency.
Differences between electric ball valves and electric butterfly valves
There are two main types of electric valves: electric ball valves and electric butterfly valves. The main materials are brass, stainless steel, and UPVC plastic. Today, we will mainly talk about the differences between electric ball valves and electric butterfly valves, and how to choose them.
The difference between electric ball valves and butterfly valves:
Firstly, from the name, it can be seen that they are all driven by electric actuators. In terms of physical structure, the structural principles of ball valves and butterfly valves are completely different. The opening and closing part of electric butterfly valves is a butterfly plate, while ball valves, as the name suggests, use a ball core as the opening and closing part. Because ball valves use a ball core, the process can be refined, so the diameter can be smaller compared to butterfly valves. This is the advantage of ball valves, but making a large diameter ball core for ball valves requires higher cost and process requirements, so this is also the disadvantage of ball valves.Compared to ball valves, butterfly valves can fully utilize their advantages and achieve large opening and closing parts. However, one advantage of ball valves is their better sealing performance compared to butterfly valves. Ball valves can withstand high pressure. However, due to the structural relationship between ball valves and the solid core material, the material cost consumed is higher than that of butterfly valves, and the price is relatively higher than that of butterfly valves.
Ball Valve
The working principle of electric ball valve:
Electric ball valves have a 90 degree rotation action, and the plug body is a ball with a circular through hole or channel passing through its axis. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media for electric ball valves. They can be tightly closed with only 90 degrees of rotation and a small rotational torque. Ball valves are most suitable for use as switches and shut-off valves, but recent developments have designed them to have throttling and flow control functions, such as V-shaped ball valves. The main characteristics of electric ball valves are their compact structure, reliable sealing, simple structure, and convenient maintenance. The sealing surface and spherical surface are often in a closed state, and are not easily eroded by media. They are easy to operate and maintain, and are suitable for general working media such as water, oil, air, solvents, acids, and natural gas. They are also suitable for harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene, and are widely used in various industries. The valve body of a ball valve can be integral or modular.
Working principle of electric butterfly valve:
Electric butterfly valve is composed of an electric actuator and a butterfly valve, which has the advantages of simple operation and structure. It is also widely used in various industrial fields such as chemical industry, medicine, water supply, power generation, etc. With the assistance of electric actuators, the development of butterfly valves has taken it to a new level. The working principle of an electric butterfly valve is to drive the valve stem through an electric device, causing the butterfly plate to rotate 90 ° to achieve the opening and closing of the valve.
