The machining department forms the core of Carilovalves’ production capability, housing multi-axis CNC turning centers and milling machines capable of achieving micron-level tolerances. Skilled technicians operate these state-of-the-art equipment to produce valve bodies, balls, stems, and end connections from raw forgings and castings. The workflow sequences operations logically: rough machining establishes basic geometries, heat treatment hardens materials, and finish machining achieves final dimensional specifications. Automated measurement systems verify every critical dimension against design tolerances, with real-time monitoring flagging any deviations before components progress to assembly.
- Turning Operations: Multi-axis CNC lathes produce spherical ball contours, stem threads, and body bores
- Milling Operations: CNC mills create port configurations, flange faces, and mounting provisions
- Heat Treatment: Automated furnaces provide consistent hardening and tempering cycles
- Surface Finishing: Grinding and polishing operations achieve required surface qualities
Assembly and Welding Processes
Clean assembly stations bring machined components together into finished valve assemblies. Assemblers follow detailed work instructions specifying torque values, lubrication points, and sequence requirements for each valve type. Critical connections employ welding techniques including TIG and MIG processes, with certified welders performing operations that require metallurgical integrity for pressure-containing joints. The welding department handles fabrication of valve bodies with integral flanges, connection fittings, and custom configurations that cannot be achieved through machining alone. Post-weld heat treatment relieves residual stresses, ensuring welded assemblies maintain dimensional stability under operational loads.
Quality Inspection and Testing Procedures
Carilovalves implements comprehensive quality inspection at multiple workflow stages, with final testing occurring before any valve receives shipment certification. Every valve undergoes 100% pressure testing using hydrostatic and pneumatic methods, with test pressures exceeding working pressure ratings per applicable standards. Seat leakage testing verifies sealing integrity under simulated operating conditions, while torque measurement confirms actuation requirements fall within specified ranges. Dimensional accuracy verification confirms critical specifications including bore alignment, seat dimensions, and flange compatibility.
| Test Type | Method | Acceptance Criteria |
|---|---|---|
| Hydrostatic Pressure | Water-filled chamber testing | 1.5x working pressure, no leakage |
| Pneumatic Seat Test | Air pressure at seat interface | Zero bubble detection |
| Torque Verification | Calibrated torque wrench measurement | Within ±10% of specification |
| Dimensional Audit | CNC CMM and manual gauges | Tolerance compliance verified |
| Material Verification | Chemical analysis and hardness testing | Certificate of conformance required |
Beyond functional testing, the quality department performs non-destructive examination techniques including ultrasonic testing for wall thickness verification and magnetic particle inspection for surface crack detection. These inspection methods identify internal and surface defects without damaging the finished valve. Certified inspectors document all test results, maintaining traceability records that accompany each valve through its operational life. The combination of 100% pressure tested products and certified quality processes gives customers confidence that every valve performing in their systems has passed Carilovalves’ most demanding scrutiny.
Finishing, Coating, and Corrosion Protection
Valves passing quality inspection proceed to finishing operations that provide long-term corrosion protection and aesthetic appearance. Surface preparation removes any remaining machining marks or handling contamination before application of protective coatings. Options include standard paint finishes, specialized chemical conversion coatings, and electroless nickel plating for aggressive service environments.
