Aluminum Valve Body Manufacturer
Bohua supplies custom aluminum valve bodies and flow-control housings with casting and CNC machining scope agreed from your drawing. Review product examples, machined ports, internal passages and the records needed to accept the finished component.
Define the component boundary early: a cast or machined valve body, its closure parts and tests, or work performed by the final valve assembler. This keeps tooling, machining, cleaning and inspection responsibilities visible in the quotation.
Bohua has two low-pressure casting machines in trial production. Part suitability, sample validation and production readiness require project-specific review before an order is accepted. Bohua does not offer sand casting.

Plan the flow passages, ports and sealing interfaces together
Flow passages and wall sections
Identify the internal passage geometry and the final machined pressure boundary.
Verification: Agree critical sections, internal inspection and functional test requirements.
Ports, threads and intersecting holes
Define port standards, thread details, intersection condition and any closure components.
Verification: Specify gauges, burr checks, closure ownership and cleaning requirements.
Seat, spool or mating bore
Provide the controlling datum, geometry and mating-part requirements.
Verification: Agree the final dimensional and surface-finish record for each critical feature.
Sealing and mounting faces
Separate sealing surfaces from mounting interfaces and cosmetic zones.
Verification: Define flatness and finish from the drawing; agree the assembled test boundary.
A drawing-specific tolerance or test requirement takes precedence over a general process description. For an observed pore, crack or leak, use the casting defect investigation guide to separate symptoms from causes. For the detailed interface review, see the valve flow-passage guide.
Agree the casting and machining scope
Identify whether Bohua supplies an as-cast component, a heat-treated blank or a finished machined part. Review material, tooling and casting allowances before defining the CNC datum and inspection plan.
- A356 material and temper: confirm the specification and required test evidence.
- Gravity casting: review geometry, cores, feeding and machining stock.
- Casting plus CNC machining: define final features and delivery condition.
Evidence to review with Bohua
The confirmed equipment list includes Oxford OES, Unicomp UNC-160 and Y.MU2000-D X-ray systems, and Hexagon Global S and NANO Metrology CMM systems.
Bohua has its own pressure-tightness testing workshop. Test method, medium, pressure, duration and acceptance criteria are defined according to customer drawings and project requirements.
PPAP documentation can be provided up to Level 5 according to project requirements.
Valve body manufacturing questions
Does Bohua supply raw or machined valve bodies?
The delivery scope can include casting, heat treatment and CNC machining as agreed for the drawing. State the delivery condition and identify finishing, cleaning, inspection and packaging requirements before comparing quotations.
How is the casting process selected for a valve body?
The review considers alloy and temper, internal passages, wall transitions, machining stock, quantity and acceptance requirements. Gravity casting is reviewed against the actual geometry. Bohua's low-pressure machines are in trial production and require separate validation; the part name alone does not determine the route.
Does a valve body quotation include complete-valve certification?
A casting or machined-body quotation does not automatically include trim, assembly, design approval or complete-valve certification. Identify the responsible party and required component tests in the project specification.
Can I verify inspection capability before releasing drawings?
Bohua has its own pressure-tightness testing workshop. Test method, medium, pressure, duration and acceptance criteria are defined according to customer drawings and project requirements. Review the quality-control and certificate pages, then request the records and equipment scope relevant to your part. Confidential drawings should follow the agreed NDA process.
