RuB, Inc.: your reliable OEM partner for custom ball valve solutions
Manufacturers frequently encounter technical requirements that off-the-shelf products cannot fully satisfy—whether due to tight dimensional constraints, specific operating conditions, material demands, or complex integration needs.
For them, finding the right valve goes beyond selecting a catalog item. It calls for engineering expertise, tailored design support, and a manufacturing partner capable of transforming technical specifications into reliable, ready-to-produce components.
Among its skills, RuB, Inc. has developed expertise for custom ball valve solutions, collaborating closely with customers to turn their requirements into fully engineered, manufacturable products designed for performance, durability, and system efficiency.
From technical requirement to engineered solution
Every project begins differently. Sometimes customers already have detailed technical drawings ready for production. Other times, the starting point is a functional need that requires a completely new product, designed and tailored to the customer’s specific application.
Our engineering team works alongside with customers from the earliest stages, assessing feasibility, defining specifications, and identifying the best technical approach. Through this process, concepts take form and develop into components ready for industrial production.
After the initial analysis, detailed 3D design is developed to validate the desired specifications and functionality in terms of space and footprint. These models are then shown to the customer for review, allowing for approval or further refinement. In some cases, prototypes may be prepared for practical fit and function tests before starting mass production.
Advanced manufacturing capabilities for custom OEM components
At RuB, Inc., we produce custom products up to 300 × 300 × 400 mm with tight tolerances. Material selection is based to application requirements and includes traditional, low-lead, lead-free, or dezincification-resistant brass, as well as aluminum alloys.
Our OEM production is fully integrated: design, machining, assembly, and testing all take place under one roof, ensuring complete control over every stage of the process. Continuous investment in dedicated machinery, advanced production technologies, and process optimization allows us to manage complex OEM projects while maintaining consistent quality and repeatability.
Today, RuB, Inc. produces over 60 million parts per year, supported by approximately 400,000 daily quality checks. Products undergo in-house cycle life testing, burst tests, bending, hardness, plating thickness, torque analysis, plus additional customer-specific checks to guarantee performance and reliability.
A long-term OEM partnership approach
Listening is a fundamental part of our OEM process. Every project starts with a deep understanding of the customer’s objectives and operational challenges. Our sales and engineering teams work as a single interface, gathering detailed application requirements and translating them into practical, manufacturable solutions through continuous cross-functional collaboration.
What defines our way of working is a true partnership mindset. For decades, at RuB, Inc. we have worked in close cooperation with customers developing OEM products, yet utilizing our high performing internal components for standardization. We combine engineering expertise and industrial know-how to address complex technical challenges, improve system efficiency, and deliver solutions that enhance equipment performance, extend operational life, and support more efficient production and cost management.
Long before customization became an industry standard, we were already working alongside partners during assembly and product adaptation phases. Today, this approach extends across the entire development process, including packaging solutions designed to meet both technical and environmental requirements, with a progressive reduction of plastic use wherever possible.
This long-term approach has made RuB, Inc. a reliable partner for manufacturers worldwide operating in hydraulic systems, HVAC, pneumatic equipment, fuel and gas distribution, sanitation systems, food service equipment, liquid filling machinery, refrigeration and firefighting applications.
