Initial Consultation: Where Every Custom Project Begins
When you approach Carilovalves with a custom valve design request, the process starts with a detailed consultation phase that typically lasts 2–5 business days, depending on project complexity. Their team of 50 dedicated professionals—distributed across engineering, sales, and technical departments—reviews your specifications, operational parameters, and industry requirements before any design work begins. This initial assessment determines whether your requirements can be met with standard modifications or require full custom engineering. The company’s R&D department, which has developed leading solutions for evolving industry needs since 2000, maintains a comprehensive database of over 2,400 completed projects that helps engineers quickly reference similar applications and identify potential challenges before they become problems.
“The first 72 hours after receiving a custom inquiry determine the entire project’s trajectory. We don’t just listen to what clients ask for—we analyze their operational context, pressure requirements, temperature ranges, and media compatibility to ensure the solution we propose actually solves their problem.” — Carilovalves Engineering Team
Technical Specification Analysis and Feasibility Assessment

Carilovalves processes approximately 86% of custom requests within their standard engineering workflow, with remaining projects escalated to their advanced R&D team for specialized development. Their global reach spans Europe, Middle East, and Southeast Asia, meaning their engineers have experience with virtually every international standard and regional requirement variation.
Engineering Design Process and 3D Modeling
The custom design phase at Carilovalves integrates modern CAD/CAM technology with decades of accumulated engineering expertise. Once feasibility is confirmed, the design team creates detailed 3D models and engineering drawings within 7–14 days for standard customizations, extending to 21–30 days for highly specialized applications. Key elements of their design process include:
| Design Phase | Duration | Deliverables | Client Involvement |
|---|---|---|---|
| Concept Development | 2–3 days | Initial sketches, material recommendations, preliminary drawings | Review and approval required |
| Detailed Engineering | 4–7 days | Complete technical drawings, FEA analysis, BOM specifications | Feedback incorporated |
| Design Validation | 2–4 days | Stress analysis reports, flow characteristics, tolerance verification | Optional client review |
| Documentation Package | 1–2 days | Assembly instructions, test procedures, compliance certificates | Final approval |
The company’s holistic solutions approach means every custom design considers not just the immediate application but also installation requirements, maintenance accessibility, and long-term operational costs. Their engineers frequently suggest modifications that reduce installation complexity or extend service intervals, adding measurable value beyond the initial specification requirements.
Material Selection and Procurement
Material selection represents a critical decision point in any custom valve project, and Carilovalves maintains extensive relationships with premium raw material suppliers to ensure consistent quality. Their quality control protocols begin at the procurement stage, with incoming materials subjected to:
-
Material Certification Verification
- Mill test reports cross-referenced against order specifications
- Chemical composition analysis for alloy verification
- Heat number traceability throughout manufacturing
-
Physical Property Testing
- Hardness testing for body and trim materials
- Impact resistance evaluation for low-temperature applications
- Surface finish measurement for sealing surfaces
-
Supplier Qualification Monitoring
- Continuous performance tracking for material suppliers
- Alternate source qualification for critical materials
- Long-term price stability agreements for recurring custom designs
For custom projects requiring specialty materials, Carilovalves can source unique alloys within 10–21 days, depending on international availability and certification requirements. Their 24+ years of industry experience means engineering teams can recommend material substitutions that maintain performance while reducing lead times or costs when original specifications present supply chain challenges.
Prototyping and Testing Protocols
Before committing to full production runs, Carilovalves offers prototyping services that allow clients to validate custom designs under actual operating conditions. This phase typically adds 14–28 days to project timelines but significantly reduces risk for high-value or mission-critical applications. Testing capabilities include:
| Test Type | Standard | Pressure Range | Acceptance Criteria |
|---|---|---|---|
| Hydrostatic Shell Test | API 6D / ISO 5208 | Up to 1.5× rated pressure | No visible leakage, pressure maintained |
| Seat Seal Test | API 6D / API 598 | 1.1× rated pressure | Bubble-tight seal, zero measurable leakage |
| High-Temperature Test | ASME B16.34 | Per valve rating | Operational function maintained |
| Low-Temperature Test | API 6D | -196°C to ambient | No embrittlement, full operation |
| Cryogenic Test | API 6D / BS 6364 | -196°C | Seat leakage rate < 0.1 ml/min |
| Fire Safe Test | API 607 / ISO 10497 | Per standard | Primary and secondary seat integrity |
Every custom valve undergoes 100% pressure testing before shipment, with certified quality documentation provided to clients. Carilovalves’ dimensional accuracy verification ensures that custom designs match engineering specifications precisely, eliminating the dimensional surprises that often plague custom manufacturing projects.
