Pressure
relief/sustaining/back pressure valve can maintain the pressure of the upstream
pipeline. It is a diaphragm type control valve controlled by
hydraulic pressure of pipeline throught pressure relief pilot. The valve can be used for pressure relief, pressure
sustaining, back pressure impact and other working conditions.

As automation continues to evolve, the demand for efficient and compact components has surged. Hollow rotary actuators have become increasingly popular due to their versatility and space-saving design. These actuators are particularly useful in applications like rotary index tables, where electrical cables or piping can pass through the central hollow bore, eliminating the need for complex mechanical parts.
Take a look at this video showcasing an articulated robotic arm assembly being rotated by a hollow rotary actuator. This technology not only simplifies setups but also ensures smooth operation and precision.
When it comes to product design, the DGII (DG2) Series hollow rotary actuator stands out. It 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 100mm, allowing ample space for cabling and piping. Cross-roller bearings provide robust support for thrust, radial, and moment loads, ensuring both accuracy and longevity. A battery-less mechanical absolute encoder eliminates the need for external home and limit sensors. With two reduction ratio options—18:1 and 36:1—belt and pulley systems are no longer necessary.
One of the key benefits of the DGII series is its flexible configurations, offering multiple ways to install these actuators. For instance, you can choose between a vertical motor mount type or a horizontal motor mount type, each with its own unique advantages.
The vertical motor mount type, as seen on the right in the image below, is ideal for those seeking a low-profile design. However, it requires cutting a hole in the mounting plate to accommodate the motor's pinion shaft facing upwards. While this works well for some applications, many users prefer avoiding the extra effort involved.
On the other hand, the horizontal motor mount type offers a simpler solution. By positioning the motor's pinion shaft sideways, there’s no need to cut a hole in the mounting plate. This configuration is especially beneficial for users who prioritize ease of installation and cost-effectiveness. Additionally, the cable outlet direction can be adjusted to either the left or right, adding further flexibility.
For those who still prefer the vertical motor mount type but wish to avoid cutting holes, an optional installation pedestal is available. Although this raises the overall height slightly to 107.5mm, it completely eliminates the need for plate modifications.
In summary, the horizontal motor mount type provides the simplest and most cost-effective solution, with a height profile of just 73mm. The vertical motor mount type remains the best option for achieving the lowest possible height (35.5mm), though it requires a mounting plate modification. Adding a pedestal allows for easy installation without cutting, albeit at the expense of a slightly taller profile.
