2-ходовые картриджные клапаны, функции давления LFA..DBEM (высокое давление)

Description Features Control cover for pressure function Product description General 2-way cartridge valves for pressure functions are pilotoperated valves in seat or spool design. The power section designed as cartridge valve (1) is installed into a receiving hole standardized according to ISO 7368 and closed with a control cover (2). The pilot control valve (4) for manual or electrically proportional pressure adjustment is integrated into the control cover (2) or is installed on the control cover (2). By combination of cartridge valves with the control covers, different pressure functions can be realized. Pressure limiting function The cartridge valve (1) for the pressure relief function (type LC . DB...) is designed as seat valve 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 the pilot control valve (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 according to the pressure-flow characteristics.
