   • Ensure that the actuator is connected to the correct pneumatic control system (typically 3-15 psi or 0.2-1 bar).
4. Valves and Accessories:
   • Install necessary accessories, such as positioners or limit switches, to optimize control and feedback in automated systems.

Maintenance Tips:

1. Regular Inspection:
   • Check the diaphragm actuator and valve assembly for signs of wear or damage, especially after extended use.
2. Seals and Gaskets:
   • Periodically inspect and replace seals and gaskets to maintain proper sealing and prevent leaks.
3. Cleaning:
   • Clean the valve periodically to remove any buildup of debris, corrosion, or other materials that could affect performance.
4. Calibration:
   • Ensure the actuator is properly calibrated with the control system to ensure accurate flow regulation.
