Pressure
differential valve is a fully automatic, hydraulic control valve. It is designed to maintain the differential pressure
between the two pipelines, so as to avoid the differential pressure exceeding
the system bearing range due to the action of other valves or the change of
flow demand. When the differential pressure increases, the valve
will open, and it will close automatically when the differential difference
drops.

Hollow rotary actuators are incredibly versatile components often used in applications like rotary index tables, where electrical cables or tubing can easily pass through the central hollow bore. Additionally, the elimination of mechanical parts like belts and pulleys by using a hollow ring gear reduces the overall footprint.
Take a look at this video showcasing an articulated robotic arm assembly being rotated by a hollow rotary actuator:
The DGII (DG2) Series hollow rotary actuator uses an AZ Series absolute stepper motor to drive a hollow output table connected to a hollow ring gear. The hollow bore diameter can reach up to 100 mm to accommodate necessary cabling and/or tubing. Cross-roller bearings provide significant support for thrust, radial, and moment loads while maintaining precision and durability. A built-in, battery-less mechanical absolute encoder removes the need for external home and limit sensors. Two reduction ratio options—18:1 and 36:1—are available to eliminate the need for additional belts and pulleys.
The original design of the DG and DG2 Series hollow rotary actuators featured a vertical motor mount type, where the motor’s pinion shaft faced upward. This configuration was ideal for those seeking a lower height profile, but it required cutting a hole in the mounting plate or table to accommodate the motor. Who wants to go through that extra hassle?
Recently, a new horizontal motor mount type has been introduced. With the motor’s pinion shaft facing sideways, there’s no longer a need to cut a hole in the mounting plate. There are two configurations for cable outlet direction: left or right.
To further enhance flexibility, an installation pedestal (an optional accessory) is available. This pedestal allows for easy installation without needing to cut a hole in the plate, though it does increase the height profile slightly.
In summary, the horizontal motor mount type offers the simplest and most cost-effective mounting solution with a reduced height profile of just 73 mm. The vertical motor mount type provides the lowest height profile of 35.5 mm from the installation plate but requires a hole to be cut. Alternatively, the vertical motor mount type can be combined with an installation pedestal, eliminating the need for cutting a hole, but increasing the height profile to 107.5 mm.
