A valve body carries the ports, the bore and the seat, and it leaks or it does not. Balford makes valve bodies two ways: machined from bar or forging, and cold formed or deep drawn into a blank which is then finish machined.
What we make
The family covers anything that routes or stops a fluid inside a machined housing.
- Solenoid valve bodies and magnetic valve components
- Hydraulic and pneumatic valve bodies
- Manifold blocks and subplates
- Valve housings supplied with the mating spring seat or spool
Two process routes
Choosing the route is a cost decision, and both routes can be quoted from the same drawing.
- Machined route: bar, forging or casting, then turning, milling, cross drilling and threading
- Formed route: cold extrusion, cold heading or deep drawing into a blank, then finish machining
- The formed route removes material cost and cycle time at volume
- The machined route is faster to first article and cheaper for low volume or late changes
What decides the function
In a valve body the leakage path is usually a geometric problem, not a material one.
- Port positions and seat face flatness held to the drawing datum
- Bore concentricity and roundness where a spool or plunger runs
- Thread form and gauge depth on every port
- Deburring and internal cleanliness before assembly
