To ensure long-term pressure containment and flawless structural integrity under industrial environments, we execute strict final inspections:
This dn80 gate valve is presented as a representative custom‑manufactured component for Industrial pipeline media; Gate‑valve body / heavy‑duty pressure‑containing valve application Honyang Cast develops similar parts from customer drawings rather than offering a fixed catalog specification.
The manufacturing plan must connect the part's functional geometry—DN80 / CL150 (Class 150); Heavy, large‑scale valve casting; Complex inner cavity; Thick‑walled sections and flanged sealing faces—with tooling, investment casting, machining and measurable inspection requirements. Final dimensions, interfaces and acceptance criteria are confirmed during drawing review.
PROJECT‑SPECIFIC SUPPLY
Material grade, dimensions, tolerance zones, machining allowance, surface condition, operating requirements and inspection records are confirmed after review of the customer’s 2D drawing, 3D model and project specification.
The parameter set is selected for this component’s function. Unknown values remain drawing‑controlled and must not be replaced with generic catalog data.

PROCESS SCOPE
Investment casting and CNC machining are described as the core route. Heat treatment, coating, polishing, balancing, pressure testing, radiographic testing, PPAP or other special processes must be shown as project‑specific unless their scope is confirmed.
Honyang Cast supports drawing‑based development of dn80 gate valve and related investment cast components from manufacturability review through sample approval and repeat production.
| Application Requirement | Manufacturing Value |
|---|---|
| Drawing‑defined fit and function | A part‑specific DFM and inspection plan links casting geometry to the actual assembly and operating requirement. |
| Integrated complex geometry | Investment casting can consolidate features and reduce fabrication or excessive stock removal where the approved design supports it. |
| Repeatable critical interfaces | Controlled datums, machining and inspection support consistent assembly of functional surfaces and mating features. |
| Material and process traceability | Agreed material and inspection records provide evidence against the drawing and quality plan. |
| Product‑specific value | Demonstrate capability for heavy, complex pressure‑boundary valve castings with soluble‑core cavity formation and downstream machining. |
