LRDS Valve

A load-sensing valve is a flow control valve that adjusts the pump displacement according to the load pressure to meet the requirements of the actuator. The pump’s flow rate is affected by an external throttle installed between the pump and the actuator, but remains unaffected by load pressure across the entire range below the set pressure. A constant-power valve maintains a constant hydraulic pump output power starting from the control initiation point within its set range; the working pressure and flow rate strictly follow a hyperbolic relationship, ensuring optimal and efficient matching with the prime mover’s power.
