Proper installation and standardized maintenance are the foundation for ensuring the long-term stable operation of sanitary valves. Before installation, the valve body and connecting pipelines should be thoroughly inspected to confirm that there are no foreign objects inside, the sealing surface is not damaged, and all components are verified to be complete. During the installation process, the manufacturer's assembly instructions should be followed, with particular attention paid to aligning flange or clamp interfaces to avoid seal failure or increased operating torque due to eccentricity. When tightening bolts, a cross sequence should be used to gradually apply force to prevent deformation caused by uneven compression. For pneumatic or electric actuators, it is necessary to ensure a clean air source, stable voltage, and complete initial position setting and action testing to verify whether the switch stroke is in place.

In terms of daily maintenance, it is recommended to develop a periodic inspection plan, focusing on observing whether there are signs of leakage in the sealing area, especially in the diaphragm plate of the diaphragm valve and the valve seat of the ball valve. Regular lubrication of transmission components can reduce the risk of wear, but it is necessary to use lubricants that meet food grade standards to avoid contaminating the medium. After each cleaning procedure, the water should be drained and dried to prevent the accumulation of water and the growth of microorganisms. If the system undergoes high-temperature sterilization, attention should be paid to the deformation reset after cooling. For vulnerable parts such as sealing rings and diaphragms, replacement records should be established to predict their lifespan based on frequency of use and operating conditions, and timely replacement should be carried out to avoid sudden failures. All operations should be performed by trained technicians and maintenance logs should be kept for traceability.
