the fork segmented structure is better than the integral rack and pinion structure. Of course, the rack and pinion hydraulic actuator can also be designed in three sections, and then various functional accessories can be designed according to the modularization. Qunmei Design and manufacture a 20,000 Nm three-stage rack and pinion structure product.

This can quickly and easily meet the various needs of users. From the perspective of manufacturing difficulty, the three-stage modular structure is easy to manufacture, the cost is better than that of the integral type, and the torque is larger, so it is popular from the perspective of cost performance. However, in some special applications, such as the marine valve application industry, the overall structure is better than the split structure. Some companies have achieved 50,000 Nm of products with a single rack and pinion structure. This output torque can cover many valve applications.

If it achieves a double rack structure, it will achieve 100,000 Nm. Many people feel that pneumatic actuators are superior to hydraulic actuators and do not need additional power sources. In fact, for pneumatic or hydraulic actuators, they all have the same function, and perform actions on the opening of the valve. They all need power, but they think that it is easy to get power, and it is troublesome to get power, and they need a separate hydraulic station.

It seems that the Globe Valve Manufacturers actuator only needs to be connected to the air circuit. Therefore, the actuator with its own power pack in the implementation of the hydraulic rack and pinion structure is more and more popular. The use of this hydraulic actuator only requires a power source, similar to a pneumatic connection with a trachea, similar to the discussion of the intelligent electro-hydraulic control before, so I won’t go into more details.
