Precision Investment Casting Stainless Steel Valve Body,Custom OEM for Ball/Gate/Globe/Check Valves
Description
-
COMPREHENSIVE SIZE AND WEIGHT RANGE: Capable of producing valve bodies from 10 grams to 300kg per piece, with maximum dimensions up to 500×500×350mm and minimum wall thickness down to 1.5-2mm . Suitable for both small precision valves and large industrial applications.
-
ENGINEERED FOR PRESSURE INTEGRITY: Designed to withstand working pressures from Class 150 to Class 2500 (PN16 to PN420). FEA-optimized wall thickness distribution ensures structural rigidity and minimal deformation under maximum rated pressure .
-
PRECISION MACHINED SEALING SURFACES: CNC-machined flange faces, seat pockets, and connection ends achieve tolerances within ±0.05mm and surface finishes down to Ra 1.6μm, ensuring reliable sealing with gaskets, seats, and mating components.
-
COMPREHENSIVE QUALITY CONTROL & NDT TESTING: Each valve body undergoes rigorous inspection including chemical analysis (spectrometer), mechanical property testing, dimensional verification (CMM available), and optional NDT examinations (Dye Penetrant Test, X-Ray, Ultrasonic Test, Magnetic Particle Test) to ensure casting integrity.
- PRECISION INVESTMENT CASTING MANUFACTURING: Manufactured using advanced silica sol lost wax casting process, ensuring complex internal geometries, smooth surface finish (Ra3.2-6.3μm), and tight dimensional tolerances (CT6-7 per ISO 8062) . The ceramic shell casting technology enables production of intricate valve body designs with minimal machining allowance
