EXCLUSION AND CONVERSION PLATES The dupromatic oleodynamic plates - blanking, cross and adaptor - are fundamental components for the functional management of hydraulic circuits in modular valves systems. The exclusion plates (blanking) serve to close unused positions or isolate sections of the circuit, guaranteeing safety and flexibility during the maintenance or reconfiguration of the system. The connection plates (cross) allow the controlled deviation of the flow, for example to create a bypass or a washing of the circuit. The reduction plate allows the transition between valves of different sizes (from ISO 4401-05 to ISO 4401-03), ensuring full compatibility between the components. All plates are supplied complete with assembly screws and garnish in NBR or FKM, for reliable performance also in heavy industrial environments.
