The MTKK / MTKL manually adjustable flow control valves are used for pressure-independent adjustment (supply) of a hydraulic actuator and thus ensure constant actuator speeds.
When the MTKK series is used with a fixed-displacement pump, it is easy to implement series circuits for hydraulic motors. The surplus flow and/or return flow can be used for the downstream hydraulic motor. The MTKL series is specially designed for use with variable-displacement pumps.
