Scotch yoke pneumatic actuator belongs to the control instrumentation series and is mainly used to regulate the flow rate. In order to make the fork actuator beautiful and safe, we should pay attention to the following principles when installing the scotch yoke pneumatic actuator:
1. Regulating valves are best installed vertically in horizontal pipelines. When horizontal or inclined installation is required under special circumstances, support should be added in addition to small caliber regulating valves.

2. When choosing the installation position of the control valve, we should strive for a straight pipe section with a diameter of less than 10D (D is the diameter of the pipeline) before and after the valve, so as to avoid the serious distortion of the working characteristics of the valve.

3. Regulating valves should be installed as close as possible to the ground or floor, but there should be enough space above and below for maintenance and repair.
4. When the caliber of the control valve is different from that of the process pipe, the conical special-shaped pipe should be used to connect the control valve, and the threaded connection should be used for the small size control valve.
5. In order to prevent the ageing of the film of the actuator, it is necessary to keep away from high temperature, vibration, toxicity and serious corrosion.
6. The direction of fluid flow should be the same as the arrow on the control valve.
7. For pneumatic regulating valves without handwheel mechanism and occasions where handwheel mechanism is an important regulating system, bypass must be adopted and cut-off valves and bypass valves must be installed. The purpose is to facilitate switching or manual operation and to repair pneumatic control valves without shutdown.
When installing the scotch yoke pneumatic actuator, Ruito's small edition suggests that you should follow the installation instructions to operate as far as possible away from high temperature, vibration, toxicity and serious corrosion occasions.
