الوصف
- We have different types of valves used in a lot of kind of industry suit any of the following applications:
- Start/stop the flow of the fluid (hydrocarbons, oil & gas, steam, water, acids) through the pipeline (example: gate valve, ball valve, butterfly valve, knife gate valve, or plug valve)
- Modulate the flow of the fluid through the pipeline (example: globe valve)
- Control the flow of the fluid (control valve)
- Change the direction of the flow (for example a 3-way ball valve)
- Regulate the pressure of a process (pressure reducing valve)
- Protect a piping system or a device (pump, motor, tank) from overpressures (safety or pressure relief) or back-pressures (check valve)
- Filter debris flowing through a pipeline, to protect equipment that may be damaged by solid parts (y and basket strainers)

HOW TO ORDER A VALVE
Manufacturers of valves used in the oil and gas industry need to know the following information to supply the right device:
- Valve type
- Bore size in NPS or DN
- Valve pressure rating (class range from 150# to 4500#)
- Specification (example API 6D, API 600, API 602, etc)
- Body and trim materials (at least)
- Required end connection (flanged, threaded, butt weld, lug and others)
- Fluid in the pipeline (>oil, gas, water, steam, solids)
- Working temperature and pressure
