Differences between Cast Valves and Forged Valves

Cast valves and forge valves are valve components produced by two different manufacturing processes. They differ in manufacturing processes, mechanical properties, and applications.

Feature	Cast Valves	Forged Valves
Manufacturing	Molten metal poured into molds	Solid metal shaped using compressive forces
Strength	Lower	Higher
Durability	Lower	Higher
Fatigue Resistance	Lower	Higher
Temperature Resistance	Lower	Higher
Cost	Generally Lower	Generally Higher
Shape Complexity	Allows for complex shapes	More limited, generally simpler shapes
Lead Time	Shorter	Longer
Applications	Low-to-moderate pressure/temperature	High-pressure/temperature, critical applications
