What is the difference between three-way merging control valves and three-way diverging control valves?
Three-way control valves, available in merging and diverging forms, consist of a pneumatic/electric actuator and a three-way merging or three-way diverging control valve. There are electric three-way control valves and pneumatic three-way control valves commonly used.
Valves are used to regulate, cut off, open the flow of liquids. They are widely applied in sugar industries for adjusting the flow of juice and water as well as regulating the steam pressure in the boiler.
The valve supply chain in foreign industrial countries is generally divided into two types of business management, one is project procurement, another is daily procurement, The related procurement policies are very different.
Valve corrosion is the leading cause of valve failure, and valve corrosion may lead to the valve’s short life and lousy performance. This artical instroduce what kind of valve corrosive and measurement to protect from valve corrosive .
In steam pipeline , steam control valve , steam ball valve , steam butterfly valve ,and check valve are the main valve . Today , let us know more about steam and steam valve .
let me show you how a pneumatic globe control valve is produced at the BCST valve factory . From order confirmed to order delivery , there are at least 9 steps for production .
Control valves are the “hands and feet” of the automation in the production process. They are used to regulate the flow in the production site and are always in contact with the medium.
The on/off valve is fully opening or closing valves in the pipeline, it can isolate a fluid totally and provide tight shut-off.The control valve is to control and regulate the flow according to the process condition, its shut off capabilities is not as good as the on/off valve.
Control valves regulate and control the flow, pressure, the temperature of a flowing fluid, such as gas, steam, water, or the chemical mixture by opening or closing internal passages. They control the amount of flow in processes. The valve stem moves, altering the size of passage, and this increases, decrease or holds steady flow.
Valve positioners are the devices that are used to put a valve in the right positioner by increasing and decreasing the air load pressure on the actuator. The valve positioner senses the exact position of the valve and communicates to the actuator to drive the valve.
