Application:
Valves serve a variety of purposes in the industrial, engineering, manufacturing and scientific communities. Selecting the right valve can determine the success or failure of the system or process.
The main purpose of a valve is to control media flow through a system. The valve may be used to start, stop, or throttle the flow to ensure safe and efficient operation of the process. Valves play a large role in most industries.   With high quality and excellent service, AFC TECH valves are widely used Oil & gas industry, refinery & petrochemical industry, off shore, power generation, mining industry, pulp and paper, water treatment etc.
