Check the operation of the valve by stroking it to full open and full close If piping system is pressurized with water for testing and in case the piping system has been shut down after testing for a long time the following recommendations should be adopted a Use corrosion inhibitor with water to pressurize the piping system b After testing the piping system should be depressurized and the test water completely drained 3 Should the valve be equipped with electric actuator please refer to paragraph 2 5 for actuator adjustment instruction 2 4 Periodic Valve Verification during Service A Normal Checks 1 Verify every month that there is no leakage from packing or in the body bonnet area If the leakage has been detected from the packing tighten the gland nuts fig 4 pos 17 slowly and evenly until the leakage stops as indicated in Table If the leakage has been detected from the body bonnet tighten the nuts fig 4 pos 10 as indicated in Table Il If the leakage does not stop it is necessary to replace the body bonnet gasket or to replace the packing 2 Every 3 6 months depending on operating frequency verify the greasing of bearings and the stem thread 3 For actuated valves in addition to above please refer also to the warnings in the actuator manual B Preventive Actions 1 Every 3 months verify the tightness of gland bolts 2 Every 6 months on motorized valves and every 8 months on hand op
