Modular Valve Assembly Segmentation for Mass Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of double block and bleed valves is complex and time-consuming due to the need for bespoke production to meet various international standards, pressure requirements, and pipeline fitting configurations, making it difficult to achieve a streamlined and efficient manufacturing process.
Innovation Solution
A modular valve assembly design where the valve body with valve balls, movement assemblies, and sealing means are formed as a unit, allowing for independent selection and fitting of the fitting means at a remote location, enabling factory testing and subsequent configuration to meet specific customer and geographical requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bespoke manufacturing is performed to meet various international standards, pressure requirements, and pipeline fitting configurations, then the valve can be customized to meet specific customer and geographical requirements, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The valve assembly is divided into modular components: a standardized valve body module and interchangeable fitting means. The valve body contains the valve ball, movement assembly, and sealing means, while the fitting means (flanges, threaded connections, weld ends) are separate attachable components. This segmentation allows the core valve function to be manufactured once and reused, while only the fitting components need to be customized for different applications.
Solution Approach 2:
The valve body is designed as a universal module that can accommodate multiple types of fitting means. The standardized interface on the valve body allows it to work with various fitting configurations (different flange types, thread specifications, weld preparations) without requiring redesign of the valve core, enabling one valve body to serve multiple functions across different applications.
2Reliability
If each valve is wholly formed and tested at the point of manufacture to meet international standards, then safety and quality requirements are met, but manufacturing time and logistics complexity increase
Solution Approach 1:
The valve body module is pre-manufactured, pre-assembled with internal components (valve ball, sealing means, movement assembly), and pre-tested at the factory to ensure it meets international standards and pressure requirements. This preliminary completion and testing of the core module eliminates the need for time-consuming on-site assembly and testing, as only the fitting means need to be attached at the installation location.
3Adaptability or versatility
If a large range of possible permutations are accommodated through bespoke manufacturing, then all customer requirements and geographical conditions are met, but the number of different valve configurations that must be manufactured increases
Solution Approach 1:
The valve system is segmented into a standardized valve body module and separate fitting means components. This allows the high-volume production of a single valve body design while enabling low-volume customization of fitting components to create the required number of permutations, dramatically improving manufacturing efficiency.
Solution Approach 2:
Only the fitting means components require customization to match specific customer requirements and geographical conditions (different materials, coatings, flange types, thread specifications). The valve body module maintains uniform quality and specifications across all applications, allowing standardized manufacturing processes while still achieving the required adaptability through localized customization of the fitting components.

AI summary
There is provided a valve assembly, the valve assembly including a body (8) in which there is housed at least one valve ball (22, 24), a movement assembly (32, 34) for moving the ball between closed and open positions with respect to a channel which passes through the body. At respective ends of the valve body there is provided sealing means (38) including a valve seat, biasing means to bias the valve seat towards contact with the ball, and at least one annular member engaged with the valve body to retain the valve seat, biasing means and at least one ball in the valve body and form a modular unit. Positioned in the valve body outwardly of each of the sealing means, there is provided a fitting means (50) engaged with the valve body and the form of the fitting means is selected and fitted to the modular unit independently of the said at least one annular member.
