Custom Stainless Steel Ball Valve Body – Investment Casting
Description
-
PRECISION CAST OR FORGED CONSTRUCTION: Manufactured using advanced investment casting (lost wax / silica sol) or hot forging processes. The ball valve body is engineered to deliver superior dimensional accuracy, smooth internal flow passages, and excellent surface finish for optimal flow characteristics and reliable sealing.
-
PRECISION MACHINED SEALING SURFACES: All critical interfaces are CNC machined to ensure perfect fitment:
-
Ball Seat Pockets: Precision machined with concentricity ≤ 0.05mm for ball alignment
-
Flange Faces: Raised face (RF), flat face (FF), or ring-type joint (RTJ) with surface finish Ra 1.6-3.2μm
-
Stem Bore: Precision bored to accommodate anti-blowout stem design
-
End Connections: ANSI B16.5 / DIN EN 1092-1 / JIS / threaded (NPT/BSPT) / socket weld / butt weld
-
-
COMPREHENSIVE QUALITY CONTROL & CERTIFICATION: Every valve body undergoes:
-
Material Verification: Spectrometer analysis with EN 10204 3.1 test certificate
-
Dimensional Inspection: CMM (Coordinate Measuring Machine) verification of all critical dimensions
-
NDT Testing: Dye Penetrant (PT) on sealing surfaces; X-Ray (RT), Ultrasonic (UT) available upon request
-
Pressure Testing: Hydrostatic shell test and seat leakage test records available
-
Traceability: Full material traceability from melt to finished product
