How to choose VALVE PARTS？

Valve parts refer to the components that make up a valve, which is a device used to control the flow of fluids (liquids, gases, or slurries) in a pipeline or system. Valves are widely used in various industries, including oil and gas, water and wastewater, chemical, pharmaceutical, and many others. Understanding the different parts of a valve is essential for valve maintenance, repair, and replacement. Here are some common valve parts:

Body: The valve body is the main housing that contains the other components of the valve. It provides the structure and connection points for the inlet and outlet pipes.

Bonnet: The bonnet is the cover or cap that encloses the internal parts of the valve, providing protection and sealing. It is usually attached to the valve body and can be removable or integral.

Disc/Closure Element: The disc, also known as the closure element, is the component that controls the flow of the fluid. It can be a gate, ball, plug, butterfly, or any other shape that can open, close, or regulate the flow by movement or rotation.

Stem: The stem connects the actuator (such as a handle, lever, or actuation mechanism) to the closure element. It transmits the force from the actuator to open or close the valve and may have a rotating or linear motion.

Seat: The seat is the sealing surface that comes into contact with the closure element. It ensures a tight shut-off when the valve is closed and prevents leakage when the valve is in the closed position.

It's important to note that valve designs can vary significantly depending on the specific application and valve type. Different valves, such as gate valves, globe valves, ball valves, and check valves, may have additional or unique parts specific to their design and function. Understanding the specific valve type and its corresponding parts is crucial for maintenance, repair, and replacement purposes.
