When selecting the valve type, many users do not know how to select the electric ball valve and the electric gate valve, and it is not known what the difference is between the electric ball valve and the electric gate valve. In response to this problem, Shanghai Huquan valve manufacturers carefully introduced the difference between the electric ball valve and the electric gate valve to facilitate more users to better know how to choose the type.
Difference between electric ball valve and electric gate valve
Electric gate valve body has a gate in the media flow direction vertical, adjust the height of the gate, you can adjust the flow of fluid. The gate valve is normally closed slower. It is generally used as the main control valve in the heating pipeline and the water supply and drainage pipeline. Electric ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
The advantages of the gate valve are its small resistance, close precision, and no water hammer. It is widely used as a shut-off valve for various liquids and gases. It also has a certain adjustment function, but when it is partially opened, the gate is easily wetted by the fluid. When the fluid flows, it can cause a chattering vibration and the sealing surface is susceptible to wear.
The gate of the electric gate valve is complex in structure, expensive and difficult to repair, and the valve seat groove is prone to deposit solid substances and is not strict.
Therefore, it should not be used in pipelines containing fibrous or solid substances in fluids. Commonly used in air, steam, oil-based medium pipelines, it is also used as a valve for venting valves and low-silk systems.
Electric gate valve is one of the commonly used shut-off valves. It is important to switch on or cut off the medium in the pipeline. It is not suitable for regulating the flow of media. The valve is suitable for a wide range of pressures, temperatures, and calibers, especially for medium and large diameter pipes.
The electric ball valve uses a ball with a center hole as the valve core, and rotates the ball control valve to open and close. Electric ball valves are used in petroleum refining, long-distance pipelines, chemicals, paper, pharmaceuticals, water conservancy, electricity, municipal, steel and other industries.
Difference between electric ball valve and electric gate valve
The structure of the electric ball valve is simple, the electric ball valve is lighter than the globe valve, the structure is relatively simple, and the weight of the group is very light, so it can play a better result in the low temperature medium system; the sealing surface is easy to process and has good sealing performance. Easy to operate, quick switch, short start-up and shut-down times, enabling rapid optimization of the test system, and no impact on the starting and closing of the valve.
But can not be used to adjust the flow, suitable for high pressure (up to 320 gauge) pipe, currently limited by the sealing material, can only be used below 200 °C, can also be used for suspension and viscosity of various media. And its regulation performance is worse than the shut-off valve, especially the pneumatic valve (or electric valve).
The difference between the electric ball valve and the electric gate valve is introduced here. After reading the above article, trusting users has already had a certain understanding of the difference between the electric ball valve and the electric gate valve.
