Cast Steel Globe Valve

Production:

Design and Engineering: The process begins with the design and engineering of the cast steel globe valve. Engineers consider factors such as pressure ratings, temperature ranges, materials compatibility, and industry standards.

Pattern Making: Once the design is finalized, a pattern is created. This pattern is a replica of the final valve shape and is used to create the mold for casting.

 Mold Preparation: The pattern is used to create a mold, typically made of sand or other mold materials. The mold is prepared, and cavities are formed based on the valve’s design.

Feature:

Melting and Pouring: Steel, often an alloy with specific properties, is melted in a furnace. The molten metal is then poured into the prepared mold.

Cooling and Solidification: The poured metal inside the mold cools and solidifies, taking the shape of the globe valve. The cooling rate is carefully controlled to ensure uniformity and minimize defects.

Shakeout and Cleaning: Once the metal has solidified, the mold is broken or shaken out to reveal the cast steel globe valve. Excess material, such as gating systems, is removed, and the rough castings are cleaned.

Heat Treatment: The castings may undergo heat treatment processes to improve their mechanical properties, such as hardness and strength.

Machining: The castings are then machined to achieve the final dimensions, including the valve seat, stem, and other critical components. This step involves precision machining tools such as lathes and milling machines.
