LRV 1 lift control valve 1 General product description. 1 6 3 Factory settings, All valves are factory set to the values for the particular installation and. then tested, S Pressure relief valve set to the maximum working pressure. S Bypass pressure as per the calculated minimum static pressure. S Emergency lowering valve set to 5 10 of maximum DOWN. S Mechanical zero point of the feedback sensor,1 6 4 Description of function. The lift control valve can be subdivided into 3 main functions. 1 UP section pressure relief valve,S Initial position. UP spool 16 is open in the 0 position pump flow goes directly to. S Up travel acceleration, UP spool 16 is progressively closed by the electro proportional.
valve UP solenoid this results in smooth acceleration of the lift up. to maximum speed,S Deceleration, UP spool 16 is progressively opened by the electro proportional. valve UP solenoid this results in smooth deceleration of the lift to. standstill,S Overload, pressure relief valve 4 and UP spool 16 open when the maximum. working pressure set with screw 1 is reached,300 I 9010050 E 28 02 2012 13 86. 1 General product description LRV 1 lift control valve. 2 DOWN section Emergency lowering valve, The down section is constructed in a similar way to the up section. S Initial position, DOWN spool 14 is closed leak free in the 0 position.
S Down travel acceleration, DOWN spool 14 is progressively opened by the electro proportional. valve DOWN solenoid this results in smooth acceleration. S Deceleration, DOWN spool 14 is progressively closed by the electro proportional. valve DOWN solenoid this results in smooth deceleration of the lift. to standstill,S Power failure evacuation, With the electrical emergency lowering valve optional the car can. be lowered using DC voltage page 48 chapter 4 2 5, S The car can be lowered slowly with the manual emergency lowering. 14 86 300 I 9010050 E 28 02 2012, LRV 1 lift control valve 1 General product description.
3 Flow rate measuring system, S The oil flows through the flow meter 12 in both the up and down. directions, S The baffle disc is displaced axially as a function of the flow rate. S This axial displacement is converted by a non contacting feedback. transducer 10 into an electrical DC signal the feedback signal. which is then sent to the DELCON, S The output signal the feedback is proportional to the flow rate. S The controller in the DELCON works to match the feedback value to. the demand signal,300 I 9010050 E 28 02 2012 15 86.
