ARON cartridge valves are basically composed of a cover and an operating unit insert in the ISO 7368 (DIN24342) mounting frame. Each cartridge valve is characterized by 2 main ways for the nominal flow (up to 350 l/min).
By combining the various covers, operating units and connections within the block, may different functions can be obtained like: direct control, non-return, hydraulically piloted non-return, pressure control, flow rate regulation, as well as a combination of these same functions.
Thanks to their design features and operational flexibility, cartridge valves can be used to speed up machine cycles, and therefore increase productivity and efficiency (Better response time compared to traditional valves);
-ensure minimum thermal dissipation (tanks to the passageway dimensions)
-reduce the hydraulic plant weight (tanks to the compact functions block)
-reduce to a minimum any internal leakages
-provide ease of installation and serving
The logic units 2/2 (Fig. 1) are formed by a cover (1), a functional unit (2), a spacer (3), a closure spring (4) and a guide bush (5) for each functional unit. The maximum allowed pressure is a function of the flow rate (max. 400 bar).
