Core Functions of Valve
Isolation:
Start or stop fluid flow within a system (e.g., ball, gate valves).
01
Regulation:
Throttle flow to control rate, pressure, or direction (e.g., globe, butterfly valves).
02
Non-return:
Prevent backflow or reverse flow in pipelines (e.g., check valves).
03
Mixing/Diverting:
Blend or reroute fluid paths (e.g., multi-port ball valves).
04
Common Types of Valve
Ball Valves
Ball valves use a spherical closure element with a bore. When the bore is aligned with the pipeline, fluid flows freely; when rotated 90°, the flow is blocked. Known for their quick operation and tight shutoff, ball valves are widely used in on/off applications requiring minimal leakage and minimal pressure drop.
Gate Valves
Gate valves operate by lifting or lowering a wedge-shaped gate to allow or block flow. They are designed for full open or full closed service and are ideal for systems that require unobstructed flow with minimal pressure loss. However, they are not suitable for throttling applications.
Butterfly Valves
Butterfly valves feature a rotating disc that controls flow by varying the angle of the disc within the pipe. These valves are compact, lightweight, and suitable for large-diameter applications. While less precise than globe valves for throttling, they are favored for fast operation and low cost.
Globe Valves
Globe valves are designed for precise flow regulation. Their disc moves vertically to throttle the fluid flow accurately, making them ideal for applications where flow rate must be finely adjusted. However, they generally have higher pressure drops compared to other types.
Check Valves
Check valves (non-return valves) allow fluid to flow in one direction only. They automatically close when backflow occurs, protecting equipment and preventing process contamination. They are commonly used in pump discharge lines and chemical systems.
The Key Components of Valve
Body:
The main outer shell of the valve that houses the internal components.
End cap:
Available in various configurations (threaded, butt weld, socket weld, flanged) and adhering to specific standards (ISO, JIS, ASME, DIN) to ensure proper sealing and connection.
Valve ball:
The central component that controls the flow, available as solid ball, hollow ball, or trunnion ball with different port options for specific applications.
Valve stem:
Often designed with anti-static features, the stem connects the operation handle or actuator to the valve ball, allowing for precise control of flow.
Ball seat:
Provides a sealing surface against the ball to prevent leakage.
Gasket:
Ensures a tight seal between components to prevent leakage.
Bolt:
Secures the components together to maintain structural integrity.
Operation:
Handle / Handwheel / Actuator. The mechanism for manually or automatically operating the valve.
Power Generation
Steam Control: Regulate steam flow to turbines and heat exchangers.
Cooling Water Systems: Control coolant circulation to prevent overheating.
Oil and Gas
Pipeline Control: Manage the flow of crude oil, natural gas, and refined fuels.
Refinery Operations: Handle high-temperature, high-pressure, and corrosive fluids.
Chemical Processing
Batch Mixing: Accurately control flow and dosing of chemicals.
Material Compatibility: Require corrosion-resistant materials to prevent leakage and degradation.
