Pambuka sing gegandhengan karo katup bola


Ingkatup bal came out in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, in just 40 years, it has rapidly developed into a major valve category. In the developed western countries, the use of katup bals is increasing year by year.
In our country, katup bals are widely used in petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries, and occupy a pivotal position in the national economy.

Ingkatup bal is most suitable for use as a switch and shut-off valve, V-shaped katup bal. In addition to paying attention to the pipeline parameters, electric valves should also pay special attention to the environmental conditions in which they are used. Since the electric device in the electric valve is an electromechanical device, its use status is greatly affected by its use environment. Under normal conditions, special attention should be paid to the use of electric katup bals and butterfly valves in the following environments.
