Investment-Cast Copper Valve Core

A core item for the internal valve mechanism, supplied to the specified component geometry. This valve core is specified in Copper. The manufacturing specification includes investment casting.

Technical Overview

• Part: Valve Core
• Material: Copper
• Processing: Investment-Cast

Valve Core Design and Assembly

• Core profile: provide the geometry of the surfaces that interact with the valve mechanism.
• Guiding fit: specify the mating bore, reference axis and any required running clearance.
• Contact features: identify edges, shoulders or other surfaces that require particular drawing controls.

Material and Manufacturing Requirements

The specified material is copper. State the exact grade and delivery condition when requesting a quotation, particularly where the material must match an existing assembly or a defined service requirement.

Investment casting is included in the specified route. Identify which features remain as cast and which require finishing so the casting requirements and final assembly dimensions can be reviewed together.

Quotation Information

Define the core profile, guiding surfaces, mating bore and contact areas. Material grade and clearances should be stated on the drawing. Include the drawing revision, required quantity and any sample or inspection documentation needed for approval.
