1. Regular cleaning of Sanitary Diaphragm Valve

Close the valve and disassemble it. Use a detergent and a soft brush to clean the valve body and diaphragm, and be careful not to damage the diaphragm. After cleaning, make sure all parts are completely dry before installing.

2. Inspection and replacement

Check the wear of the diaphragm: Check the wear of the diaphragm regularly. If cracks, deformation or severe wear are found, it should be replaced in time.
Check the sealing performance: Check the sealing performance of the valve. If there is leakage, replace the seal or adjust the valve clearance.

3. Lubrication and tightening

Lubricate the moving parts: Apply an appropriate amount of lubricating oil to the moving parts such as the valve stem and valve cover regularly to reduce friction and wear.
Check the fasteners: Check the fastening of fasteners such as bolts and nuts regularly. If looseness is found, tighten them in time.

‌Fourth, Storage and Protection‌

‌Storage environment‌: Sanitary diaphragm valves should be stored in a dry and ventilated room. Stacking is strictly prohibited. The channels at both ends of the stock diaphragm valves must be sealed, and the opening and closing parts should be in a slightly open state‌.
‌Protective measures‌: For sanitary diaphragm valves installed outdoors, a protective cover should be installed on the valve stem to protect it from rain, snow, dust and rust‌.

‌Five, Other precautions‌

‌Avoid long-term opening‌: When the sanitary diaphragm valve is opened for a long time, dirt may stick to the sealing surface. When closing, the valve can be gently closed first, then opened a little, and the dirt can be washed away by the high-speed flowing medium, and then closed tightly‌.
‌Add lubricating oil‌: The valve stem thread often rubs against the valve stem nut. A certain amount of oil should be maintained at the screw to lubricate and ensure the free movement of the valve stem‌.

Follow the above use and maintenance guidelines to ensure the normal operation of the sanitary diaphragm valve and extend its service life.
