How Carilo Valve’s Design Software Streamlines Custom Valve Creation
Carilo Valve’s proprietary design software fundamentally transforms the custom valve creation process by acting as a centralized, intelligent platform that integrates every stage from initial concept to final manufacturing specifications. It replaces a traditionally fragmented, error-prone workflow involving manual calculations, 2D drafts, and countless email exchanges with a unified digital thread. This system is engineered to capture complex customer requirements—such as pressure ratings, flow coefficients (Cv), temperature extremes, and media compatibility—and instantly translate them into a validated, optimizable 3D model and a corresponding bill of materials. The core value lies in its ability to drastically reduce lead times from weeks to days, minimize human error, and empower engineers to explore more design iterations to achieve peak performance. You can explore the platform’s capabilities directly on the Carilo Valve website.
The software’s foundation is a sophisticated rules-based engine that codifies decades of engineering expertise and industry standards like ASME B16.34 and API 6D. When a design engineer inputs parameters, the software doesn’t just draw a shape; it performs real-time analysis. For instance, if a user specifies a 10-inch ball valve for 600 PSI service with sour gas (containing H₂S), the software automatically selects materials compliant with NACE MR0175/ISO 15156, calculates the required wall thicknesses to prevent sulfide stress cracking, and recommends appropriate trim and seal materials like Inconel 718 or PTFE. This proactive compliance checking ensures that the valve is not only functional but also inherently safe and certified for its intended harsh environment.
One of the most significant advantages is the parametric modeling capability. Instead of designing each valve from a blank slate, engineers work with a dynamic model where key dimensions and features are driven by variables. Changing the valve’s nominal diameter from 4 inches to 6 inches automatically and intelligently adjusts the flange dimensions, stem diameter, and actuator mounting pad, while maintaining all structural integrity. This allows for rapid “what-if” scenarios. The table below illustrates how a single parameter change cascades through the design, with the software ensuring all components remain in harmony.
| Primary Parameter Change | Automated Adjustments by Software | Impact on Performance |
|---|---|---|
| Pressure Rating: 150# to 300# | Flange thickness increases by 35%, bolt circle diameter expands, stem diameter increases by 15%. | Leak-proof integrity at higher pressures; 20% increase in structural safety factor. |
| Flow Requirement (Cv): 200 to 350 | Port diameter increases, valve body cavity is redesigned for streamlined flow, trim is optimized. | Reduces pressure drop by approximately 40%, minimizing energy loss in the system. |
| Temperature: -50°C to 200°C | Material selection shifts from carbon steel to 316 Stainless Steel, gasket material changes from EPDM to Graphite. | Eliminates risk of brittle fracture at low temps and maintains seal integrity at high temps. |
Beyond geometry, the software is deeply integrated with analysis tools. It can run Finite Element Analysis (FEA) simulations internally to predict stress concentrations under load, something that previously required exporting models to specialized (and expensive) third-party software. For a high-pressure gate valve, the software might simulate a 2500 PSI hydrostatic test, visually highlighting areas of high stress near the seat rings. The engineer can then add localized reinforcement or fillets directly within the same environment, re-run the simulation in minutes, and confirm the design’s robustness before a single piece of metal is cut. This virtual prototyping slashes development costs and prevents costly physical test failures.
The platform’s utility extends directly into manufacturing and supply chain management. Once a design is finalized, the software does not simply output a generic CAD file. It generates a complete digital twin that includes:
- CNC Machining Code: Toolpaths for milling the valve body from a raw forging are generated automatically, reducing machine programming time by over 80%.
- Component-Specific Drawings: Detailed drawings for every part, with full Geometric Dimensioning and Tolerancing (GD&T), are created instantaneously.
- Intelligent Bill of Materials (BOM): The BOM is not a static list; it’s a live document linked to inventory systems. It specifies part numbers, materials, and can even trigger alerts if a required stainless steel grade is running low, suggesting approved alternatives.
This seamless data flow eradicates the translation errors that often occur when engineering “throws a design over the wall” to the production team. The manufacturing team receives a ready-to-execute package, ensuring that the valve built on the shop floor is a perfect physical manifestation of the digital design. For complex multi-part assemblies like control valves, the software can also generate animated assembly instructions, which visually guide technicians through the correct installation sequence of diaphragms, springs, and positioners, thereby improving quality control.
Collaboration is another cornerstone of the software’s design. It operates on a cloud-based platform where multiple stakeholders—the customer’s project manager, Carilo’s design engineer, and a third-party inspector—can all view and annotate the same 3D model in real-time. Comments and markups are tracked directly on the model, creating a transparent audit trail. For example, an inspector can virtually “redline” a weld joint and request a specific non-destructive testing (NDT) method, and the software will log this requirement directly into the valve’s digital history file. This centralized communication prevents the common pitfalls of version control issues and ensures everyone is aligned throughout the project lifecycle.
Finally, the software contributes significantly to lifecycle management and sustainability. Each custom valve design is stored in a searchable digital library. If a customer needs an identical or similar valve five years later, the original design can be retrieved, modified if necessary, and put back into production with minimal effort. This preserves engineering intellectual capital. Furthermore, by optimizing material usage through precise simulations—for example, using topology optimization to remove unnecessary metal from a valve bonnet without compromising strength—the software actively contributes to reducing the product’s weight and raw material consumption, aligning with modern environmental and efficiency goals.
