Описание Особенности Управляющая крышка for pressure function Описание продукта General 2-клапаны картриджного типа for pressure functions are pilotoperated valves in seat or spool design. The силовая часть designed as cartridge valve (1) is installed into a приёмное отверстие standardized согласно ISO 7368 и закрыта крышкой a управляющая крышка (2). The pilot control valve (4) for manual or electrically proportional pressure adjustment is integrated into the управляющая крышка (2) or is installed on the управляющая крышка (2). By combination of cartridge valves with the control covers, different pressure functions может быть realized. Pressure limiting function The cartridge valve (1) for the pressure relief function (type LC . DB...) is designed as седельный клапан without area difference (no effective area at port B). The effective pressure at port A is directed via the pilot oil supply orifice (5) to the spring side (6) of the element. Under the pressure set at пилотный распределитель (4), the spool (3) is pressure-compensated and closed by the spring force. On reaching the set pressure, the spool (3) is opened and the pressure at port A is limited согласно the pressure-flow characteristics.
