<p>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.</p> |
