Valve Seat Leakage Test What is Valve Seat Leak Test

The bubble test used for Class VI seat leakage is based on the leakage rate of air or nitrogen gas past the closed valve seat as measured by counting the rate of gas bubbles escaping a bubble tube submerged under water..For a 6 inch valve,this maximum bubble rate is 27 bubbles per minute (or about 1 bubble every two seconds):Vacuum Ball Valves McMaster-CarrThreads and a hex nut below the handle allow you to install these valves in instrument panels.For extra gripping power and a strong seal,they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut.All are compatible with Swagelok ball valve airtight test 0 5~0 7#174;,Let-Lok,and Parker A-Lok fittings.Use these valves with water,oil,air,inert gas,and steam.VALVE FIRE TEST DOWNSTREAM SEALING BALLAllowable rate is 25.0 ml/min/NPS.4.Valve Operation After Fire Test The valve was capable of being unseated against high-test pressure differential and moving to the full open position and back to the full closed pOSition.5.Operational Test,Following Cooldown a.Average through leakage rate of 1.0 ml/min/NPS occurred during 5.00-minute
