Abstract (en)
[origin: CA2049792A1] The valve consists of two proportional throttle valves with which is associated a non-return valve on the outlet side and of two seat valves pilot-controlled by the proportional throttle valves, all of which are accommodated in a valve housing with standardised interface. The proportional throttle valves have a magnetic control such that each function of a hydraulic cylinder can be proportionally controlled and regulated.
Abstract (de)
Das Ventil besteht aus zwei Proportional-Drosselventilen (C1, C3) denen austrittseitig ein Rückschlagventil (R1, R3) zugeordnet ist und aus zwei durch die Proportional-Drosselventile vorgesteuerten Sitzventile (C2, C4) welche alle in einem Ventilgehäuse mit genormter Schnittstelle untergebracht sind. Die Proportional-Drosselventile (C1, C3) besitzen eine magnetische Aussteuerung wobei jede Funktion eines Hydraulikzylinders proportional angesteuert und geregelt werden kann. <IMAGE>
