TurkishIn 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 .
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 actuator is the element to open and close a valve . It is a must element for any valve .
There are mainly four types of actuators: manual, pneumatic, hydraulic, and motorized (electric ).
Control valve is a power-operated device used to modify and control the fluid flow rate in a process system .
