The MTKA manually adjustable flow control valves are used for pressure-independent adjustment (supply) of a hydraulic actuator and thus ensure constant actuator speeds. MTKA flow control valves can be used for 2-way or 3-way operation. As the 3-way version, they divide the inlet flow into a constant-flow / priority-flow portion and a surplus-flow portion. The surplus flow can be pressurized and can therefore be supplied to a second actuator.
