Globe valve internals | Globe valve vs ball valve - CNC Prog

Material of Globe valve internals is stainless steel, bronze, or cast iron. It Contains the inlet and outlet ports for fluid flow.

Component	Function
Valve Body	Provides structure and controls the fluid flow path.
Bonnet	Seals internal components and allows maintenance access.
Valve Stem	Transfers motion to the valve plug, regulating flow.
Plug	Controls fluid flow by sealing against or allowing passage through the valve seat.
Valve Seat	Provides a sealing surface to prevent fluid flow when the valve is closed.
Packing & Gland	Prevents leaks around the valve stem and ensures smooth operation.
Actuator	Automates valve operation for precise flow control.
Handwheel/Lever	Allows manual control of the valve for flow regulation.
Flow Pattern	Determines how fluid flows through the valve, affecting pressure drop and throttling.

Why Globe Valve Internals Matter

Benefit	Description
Flow Control	Precise control over fluid flow, making globe valves ideal for throttling applications.
Durability	Designed to withstand high pressures and corrosive fluids, ensuring long-lasting performance.
Leak Prevention	Seals prevent leaks, maintaining system integrity and reliability.

Globe valve vs ball valve

Feature	Globe Valve	Ball Valve
Flow Control	Excellent for precise flow regulation and throttling.	Best for on/off control, not ideal for throttling.
Pressure Drop	Higher pressure drop due to complex internal flow.	Lower pressure drop with a straight-through flow.
Seal Tightness	Provides tight seal when fully closed.	Reliable seal but designed for on/off, not throttling.
Operation	Manual or automated with linear motion.	Manual or automated with quarter-turn (rotary motion).
Size & Cost	Larger and more expensive, especially in high-pressure apps.	Compact and cost-effective for on/off control.
Maintenance	Requires more maintenance, especially in throttling apps.	Low maintenance due to fewer moving parts.
Applications	Used for flow regulation (e.g., steam, water, gas).	Ideal for quick shutoff (e.g., pipelines, water).
Durability	Durable but subject to wear in throttling use.	Highly durable with minimal wear in on/off applications.

When to Choose:

Globe Valve: For precise flow control and throttling.
Ball Valve: For quick shutoff and minimal maintenance.
