Drawing-based pump wear components and hardfaced valve trim
Small and medium batch machining for pump and valve sleeves, collars, washers, spacers, wear rings, bushings, glands, balance parts, valve components and special pump OEM components.
Finished valve seat and seat-ring components
Finished valve seats with confirmed Stellite 6 and Ni60 surface requirements
The gallery's Stellite 6/ST6 and Ni60 labels apply only to the matching verified examples and order requirements.
RF Machining supplies drawing- or sample-based finished components, not complete valves. Responsibility for complete-valve design, the pressure-retaining boundary, assembly, pressure testing, certification and valve performance remains with the valve manufacturer or design authority. Seat and seat-ring terminology is applied according to the component geometry and the customer's valve drawing.
RF Machining reviews a seat or seat ring according to the geometry named in the customer drawing, including the marked seating or working surface. Supply may start from a drawing, 3D model, sample or sample photos, but final production requirements must be confirmed. Applicable hardfacing routes are reviewed for each component and order. The route, filler/consumable grade, hardness, allowance, finished overlay thickness, dilution when applicable, finish machining and inspection are confirmed per drawing/RFQ/order.
These are verified diesel-engine valve-seat examples with specified Stellite 6 on the tapered surface and Ni60 thermal spray in the bore. They are not presented as control-valve seat examples. Applicability and the manufacturing route remain drawing- and order-specific.
Yes. RF Machining supplies drawing- or sample-based finished components when the seat or seat-ring geometry, base material, hardfaced area and final requirements are defined and accepted.
Not automatically. RF Machining follows the customer's drawing and component geometry, using seat or seat ring according to the identified part rather than treating every seating component as the same geometry.
No. Those photos are adjacent application examples only and are not presented as control-valve seat examples.
No. Those labels belong only to the matching verified gallery examples and order requirements. Stellite is an RFQ-specified trade-name family and is not a generic name for all cobalt alloys.
No universal hardfacing route is promised. Applicable hardfacing routes are reviewed for each component and order. The route, filler/consumable grade, hardness, allowance, finished overlay thickness, dilution when applicable, finish machining and inspection are confirmed per drawing/RFQ/order.
No. RF Machining supplies drawing- or sample-based finished components, not complete valves. Responsibility for complete-valve design, the pressure-retaining boundary, assembly, pressure testing, certification and valve performance remains with the valve manufacturer or design authority.
