Definition of valve :
A valve is a mechanical device that controls the flow of liquids, gases, or slurries through pipes or vessels by opening, closing, or partially obstructing passageways. Valves are used to regulate, direct, or control the flow of fluids within a system.
Types of Valves in oil and gas :
Deffintion and function
Ball Valve:
Definition: A ball valve uses a hollow, perforated, and pivoting ball to control the flow of fluid. When the valve is open, the hole in the ball aligns with the flow path, allowing fluid to pass through. When the valve is closed, the ball rotates to block the flow.
Function: It provides a quick and tight shut-off, ideal for on/off applications.
Use: Commonly used in oil, gas, water, and chemical industries due to its durability and reliable sealing performance.
Gate Valve:
DEFINITION Of Valve : A gate valve uses a wedge-shaped metal gate to control fluid flow. The gate moves up and down to open or close the valve.
FUNCTION OF VALVE : Primarily used for isolation or on/off control. It allows full flow when open and provides minimal resistance.
Use: Used in pipelines that require a valve to remain fully open or closed, such as in water supply, oil, and gas pipelines.
ESDV (Emergency Shut Down Valve):
DEFINITION OF ESDV:
An Emergency Shut Down Valve (ESDV) is designed to rapidly isolate a section of a pipeline or system in the event of an emergency to protect equipment or personnel.
Function: It shuts down the flow in case of an emergency, preventing damage, leaks, or hazardous situations.
BASIC USE.
Essential in industries such as oil & gas, petrochemical, and chemical processing where rapid shutdown is crucial for safety.
MOV Valve (Motor Operated Valve):
Definition of Mov
A Motor Operated Valve (MOV) is a valve that is operated by an electric motor instead of manual force. It can be remotely controlled to open or close the valve.
Function: Typically used for automatic control in complex systems, especially for large valves that are hard to operate manually.
Basic use : Common in water treatment plants, oil refineries, and power stations, where remote and automated control of fluid flow is necessary.
