The spool types 6A and 6D are designed to supply 2 motorized drives. By dividing the control spool 6A, 2 motorized drives can be implemented in parallel, and independently of one another, in one valve body.
Pressure, make-up function
The pressure control valves protect actuators from unacceptably large pressure peaks when the actuator is operated or when external forces act on the actuator. The make-up function supplies oil to the actuator when the tank pressure is higher than the actuator pressure.
