We have three Mueller 60" Lineseal III Butterfly Valves in our cooling tower. Recently, we were informed that we could not longer obtain the seal and bolt kits for these valves from Mueller as they no longer make the valves. The bolt kits are a lower priority, but we need the seals for our...

I am looking to attend a good combustion training course in Canada or the US. Have you attended one recently that you thought was particularly useful? Do you have the info on who put on the course and what topics were covered? I'm looking at everything from basic combustion theory to...

I have a shaft that I suspect may have an eccentricity problem, and I am wondering if there is a procedure for checking for eccentricity with a strobe light. It is a three piece shaft through a screw pump. We could use a dial indicator on the straight stubs at the ends, but the centre section...

I have a universal joint connecting an actuator to a valve, and I need to determine if it's installation location does not cause the joint to exceed the maximum angle for that type of joint. Does anyone have a good reference that would give minimum and maximum angles for proper operation of a...
