The M4 valve delivers 6-200L/min flow with load-sensing (LS) control. The main spool regulates flow and direction, adjusted by pressure-reducing valves based on electric current. PMC enables precise spool position control. Pre-compensation ensures constant flow regardless of pressure changes. LS pressure relief valves protect ports A and B from surges. Stroke limiters allow mechanical flow adjustment, and the highest load pressure is signaled to the pump via the LS line for optimized load response.
Product Introduction
Actuator Control
- » Main spool determines the direction and the amount of flow that is directed to the actuator ports.
- » Pressure reducing valves control the position of the main spool. The intensity of the electric current on the pressure reducing valve determines the amount of the pilot pressure in spring chambers and hence the stroke of the main spool.
- » The position control stroke of the main spool can be operated by PMC.
- » Pressure compensator keeps the pressure differential across main spool and consequently the flow to the actuator constant.
Load Pressure Compensation- » Pressure changes in the actuators or the pump are corrected by the pressure compensator.The flow to the actuator remains constant even under differing loads.
Flow Limitation- » The maximum flow can be adjusted mechanically and individually by means of stroke limiters.
Pressure Relief Function
- » The LS pressure per actuator port can be influenced internally by means of LS pressure relief valves or externally via LS ports MA,MB.
- » Pressure relief/anti-cavitation valves protect actuator ports A and B from pressure peaks and from external forces. The highest load pressure is signalled to the pump via the LS line and integrated directional valves.
