Assembly option for hydraulic control valves whereby a valve is assembled in each case on a mounting subplate containing up to five ducts and it is possible to bolt them together as required. It ends
with two end plates (Figure L 3). A series connection can be combined as required — for example, by inserting a plate with throttle valves or — with a parallel connection.
The sandwich design associated with mobile hydraulics is a form of series connection. Individual components incorporating complex hydraulic functions are combined into a control block. Valve functions are also integrated into the end plates. They are referred to as a pump mounting module or input element and as an end section or output element.
