What is Parts-in-Body Technology
In general, there are three possible designs for hydraulic manifolds. In Industry the most common design is the CETOP construction, where valves are mounted on a subplate with a standardized valve hole pattern. In mobile technology or in case of medium quantities screw in cartridge technology is often used. This of course leads to smaller and more compact valve blocks. In case of medium to high quantity demand special customized parts-in-body-design is beneficial. With parts-in-body technology, a very compact block design can be achieved while maintaining customer specific block dimensions.
Advantages of Parts-in-Body-Design
The advantages of parts-in-body design are shown in the following enumeration.
Realization in Casting
Parts-in-Body design can be realized in standard milled and honed manifold design. But it also is possible to base the design on a casting blank. Subsequently examples of a casting design are shown.
Customized Valve Design by Means of CFD Flow Simulation
In many cases, the standard block design with cartridge or CETOP valves is not sufficient and must be supplemented with special functions. A parts-in-body block design can then be a solution, as the freedom of parts-in-body enables our engineers to design and optimize customer specific blocks. Fluitronics uses flow simulation, Computational Fluid Dynamics (CFD) to minimize pressure losses in the manifold and determine valve behavior and valve forces in advance. For this purpose, the flow path is divided into a mesh of many thousands of small units that are mechanically linked to each other. Based on the given boundary parameters, the CFD simulation software solves a complex system of equations and thus determines flow lines and pressure losses along these lines. Based on these results, we then work with our customers to determine a design that meets their needs.
