①The valve should be kept clean and stored in a dry room; ② long-term storage of the valve should be regularly checked and repaired, remove the sealing surface and the valve body oxidation rust, regular replacement of the aging rubber diaphragm; ③ Before installation should valve cavity And the connection sealing surface according to the requirements of vacuum cleaning; ④ valve installation location can be installed in any direction as needed; ⑤ valve after inspection and assembly, the vacuum performance test. The possible failure of the valve and its elimination are shown in the following table. Possible Causes of Malfunctions Elimination Method Malfunctions 1. Dirt on the sealing surface 2. Damaged sealing surface 3. Damaged or aged diaphragm 1. Clean the dirt 2. Refurbish or replace 3. Replacement Can not be closed or not open or close 1. Stem on the valve has twisted or plotted dirt 2. Stem nut thread has serious wear or tear 3. Stem hurdle 1. Maintenance thread or remove dirt 2. Replace the stem nut 3. Calibrate the stem or replace the new may occur down the cause of the failure to eliminate the bad seal 1. sealing surface with dirt attachment 2. sealing surface damage 3. membrane damage or aging 1. The dirt Clean 2. Refurbishment or replacement 3. Replacement of the new opening and closing is not flexible or can not be opened and closed 1. The thread on the stem is damaged or there is dirt 2. The thread of the stem nut is severely worn or broken 3. The valve Rod Hurdle 1. Repair thread or remove dirt 2. Replace stem nut 3. Calibrate stem or replace
