Solution Overview
Problem
Existing pressure relief and pressure control valves are designed individually for each application, leading to high production and maintenance costs due to the multitude of structural components and the need for complete valve replacement upon damage.
Innovation Solution
A modular valve system with standardized valve housing and components, such as a valve piston and pilot control element, allowing for adaptation to different fluid flows and applications using a limited set of structural components, including energy accumulators and proportional magnets with varying characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pressure relief and pressure control valves are designed individually for each application, then the valves can be precisely adapted to specific fluid flows and applications, but production costs and maintenance costs increase due to the multiplicity of valve structural components
Solution Approach 1:
The patent implements a universal valve body design that can accommodate multiple different valve components and configurations. The standardized valve body with consistent mounting interfaces allows a single base structure to serve multiple applications by simply changing the valve components, thereby reducing the overall number of unique parts while maintaining application-specific functionality.
Solution Approach 2:
The valve system is divided into modular components including a standardized valve body and interchangeable valve components. This segmentation allows individual components to be replaced or modified without affecting the entire valve assembly, reducing maintenance costs and enabling precise adaptation to different applications through component selection rather than complete redesign.
2Reliability
If pressure relief and pressure control valves are designed individually for each application, then precise control is achieved, but complete valve replacement is required when a valve is damaged, increasing maintenance costs
Solution Approach 1:
The valve is designed as an assembly of interchangeable components mounted on a standardized valve body. When a component becomes damaged, only that specific component needs to be replaced rather than the entire valve, significantly reducing maintenance costs and downtime while preserving the precision control characteristics of the original design.
3Productivity
If individually designed valves are used for each application, then optimal performance is achieved, but storage of individual components becomes too costly due to the large number of structural components
Solution Approach 1:
By implementing a universal valve body design with standardized interfaces, the system reduces the total number of unique components that need to be stored. The same valve body can support multiple different valve configurations, allowing organizations to maintain inventory of fewer base components while still being able to address various application requirements through component interchangeability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables cost-effective production and maintenance by allowing a small number of components to control multiple applications, reducing the need for multiple valve designs and facilitating easy modification and repair.
Implementation Method 1
The electrically actuated valves are actuated by a magnet, usually one in the form of a proportional magnet system
Implementation Method 2
the difference in pressure between beginning and end of opening is very small

AI summary
A modular valve system includes at least one valve housing (40) having standard rate quantities on its opposite ends (38, 42), both on the inner peripheral side and on the outer peripheral side and inside the housing (52). Modular valve components, such as a valve piston (46), at least one energy accumulator (26), a pilot-controlled element, and at least one fluidic connection are mounted in the housing. The housing provides for fixing the valve embodied in the form of a screw-in cartridge for connection to other components.
