Legacy Valve Sizing Tool Transformed into a Secure Web-Based Platform
Client Overview
A leading industrial valve manufacturer specializing in control valves for critical applications. The client relied on a custom-built VB6 desktop application for internal valve sizing and selection for over a decade.
Business Challenge
Over the years, the client’s desktop-based VB application became increasingly difficult to maintain and expand. The main challenges included:
- Restricted Accessibility
The application was installed on individual PCs, making it difficult for distributed teams and sales partners to use it efficiently. - Outdated Technology Stack
Built on Visual Basic 6.0, the application lacked support, security updates, and modern integration capabilities. - Scattered Data
Sizing results, pricing, and quote data were stored locally, with no central access or traceability. - Difficult to Extend
The app couldn’t support newer requirements like actuator logic, PDF generation, or multi-user access without significant workarounds.
- Security Limitations
The company needed a modern, web-based solution that aligned with its digital transformation goals.
Our Solution: Complete Modernization Using ASP.NET
We helped the client migrate to a scalable, secure, and user-friendly web platform, purpose-built for valve sizing, selection, and quoting.
Key Enhancements Delivered:
- Full Functional Migration
Converted all legacy sizing logic — including Cv, ΔP, Flow %, and actuator calculations — into modern ASP.NET backend with SQL Server. - Modern, Responsive UI
Delivered a clean and intuitive user interface with improved workflows, dark/light mode, mobile compatibility, and interactive form validation. - Web-Based Access
Accessible via any browser without installations — supports distributed teams and global sales partners. - Centralized Database with Audit Trails
All projects, sizing data, and quote records are stored securely in a central SQL Server database, enabling real-time tracking and version control. - Built-in Document Generator
Users can generate datasheets and quote PDFs directly from the application, with branding and technical details auto-filled. - Expandable Architecture
Designed to scale with future needs — from multi-language support to integration with CRM or CPQ modules. - Enterprise-Grade Security
- Integrated with Active Directory (AD) for centralized user management.
- Enabled Multi-Factor Authentication (MFA) for added login security.
- Role-based access control ensures data protection and internal compliance.
