Investment-Cast Stainless Steel Butterfly Valve

A butterfly valve part whose disc, stem and body interfaces must match the selected valve assembly. This butterfly valve is specified in Stainless Steel. The manufacturing specification includes investment casting and precision machining.

Technical Overview

• Part: Butterfly Valve
• Material: Stainless Steel
• Processing: Precision Machined, Investment-Cast

Butterfly Valve Design and Assembly

• Disc relationship: identify the mating disc and body clearance required by the valve design.
• Stem connection: define shaft alignment, attachment features and operating interfaces.
• Sealing arrangement: specify the relevant contact surfaces and the seal design used in the complete assembly.

Material and Manufacturing Requirements

The specified material is stainless steel. 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.

Precision machining is specified for this component. Identify the critical dimensions, their reference datums and the surfaces requiring a defined finish so the quotation reflects the functional requirements of the actual part.

Quotation Information

Supply the disc or body drawing, shaft connection details and sealing requirements. Operating ratings must be agreed for the finished valve. Include the drawing revision, required quantity and any sample or inspection documentation needed for approval.
