Elbow Globe Valve Vertical Actuator Angular Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional globe valves require horizontal actuator installations to achieve angular changes in fluid flow, which lead to inefficiencies, such as erosion and swirling, and reduce valve performance due to side loading and gravity-related issues, while maintaining an actuator-vertical orientation is challenging and limited to strict 90-degree turns.
Innovation Solution
A globe valve assembly with a vertically oriented actuator and angularly offset inlet and outlet flow orientations, enabled by modern casting and additive manufacturing, allowing for customizable 360-degree angle relationships and top-entry trim for simplified maintenance, eliminating the need for piping elbows and reducing recirculation cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional globe valves use horizontal actuator installation to achieve angular changes in fluid flow, then angular flow change is achieved, but valve performance deteriorates due to side loading and gravity-related issues
Solution Approach 1:
The patent inverts the conventional actuator orientation from horizontal to vertical. By installing the actuator vertically, the valve stem and plug alignment are optimized to eliminate side loading and gravity-related performance issues while maintaining angular flow change capability through the elbow configuration of the valve body
Solution Approach 2:
The patent merges the function of the globe valve with an angular piping transition (elbow) into a single integrated component. The valve body incorporates both the flow control function and the angular direction change function, eliminating the need for separate piping elbows and achieving angular flow change without compromising valve performance
2Reliability
If conventional globe valves maintain actuator-vertical orientation, then valve performance is improved, but angular flow change is limited to strict 90-degree turns
Solution Approach 1:
The patent introduces adaptability into the valve design by allowing the angular orientation to be customized based on application requirements. While maintaining vertical actuator orientation for optimal performance, the valve can be configured with different angular offsets (e.g., 90 degrees, 45 degrees, or other angles) to match various piping arrangements, making the solution dynamic and adaptable rather than fixed
3Adaptability or versatility
If conventional globe valves use separate piping elbows for angular transitions, then angular flow change is achieved, but device complexity and piping expenses increase
Solution Approach 1:
The patent combines the globe valve body with an integrated elbow section into a single unified component. This merger eliminates the need for separate piping elbows and reduces the number of connections and components required, thereby simplifying the overall piping configuration and reducing device complexity while maintaining angular flow change capability
Solution Approach 2:
The valve design serves multiple functions simultaneously: it provides flow control through the plug and seat mechanism, achieves angular direction change through the integrated elbow configuration, and eliminates the need for additional piping components. This multi-functionality reduces overall system complexity and piping expenses

AI summary
A globe valve assembly can include a globe valve that can include a valve stem that defines a valve stem axis, a valve seat, a plug secured at a distal end of the valve stem, and a valve body that supports the valve seat. The valve body can define an inlet passage that extends between an inlet opening and the valve seat and an outlet passage that extends between an outlet opening and the valve seat.
