What is a hydraulic valve body?
A hydraulic valve body is a machined housing that provides bores, cavities, ports, passages, sealing interfaces and mounting features for a specific valve design.
What hydraulic valve body designs can you machine?
We can review drawing-specific direct spool-bore, sleeve-type, cartridge-cavity and poppet or seat valve bodies when mating component data and acceptance criteria are provided.
Which materials are available?
Common options include carbon steel, stainless steel and aluminum alloy. Alloy steel, cast iron or ductile iron can be reviewed when project requirements are defined.
What information is required for quotation?
Please provide current drawings, models, schematics, revision data, mating components, material and finish requirements, critical features, quantities, inspection scope and samples when available.
How are valve bores, ports and internal passages inspected?
Inspection follows the drawing and agreed inspection plan, covering critical bores, cavity features, port positions, passage relationships, sealing interfaces and final dimensions.
How are cross-hole burrs and cleanliness controlled?
Cross-hole deburring and cleaning requirements are reviewed by drawing or order scope, with functional surfaces protected after specified cleaning.
Are hydraulic valve bodies pressure or function tested?
Bare-body inspection confirms machining features only. Pressure, leakage, flow and function testing must be validated on the completed valve assembly when required by the customer design and test plan.
How is a valve body different from a hydraulic manifold block?
A valve body directly houses or interfaces with moving or sealing valve elements; a manifold block primarily integrates passages and mounting interfaces for multiple hydraulic components.
