Does any know if there is any guide for valve packing selection based on service and temperature?

I am involved in developing a lift and turn plug valve for sand/slurry application. My job is to functionally test our design and give feedback.

I need some insight on specifically what happens at the plug when the gaps cannot be fired for any reason such as a very lean misture, excessive gap or a short.

've recently serviced two desuperheater control valves (boiler feed water service) which were found passing, and the immediate cause was erosion at plug and seat. Currently we suspect that the erosion

Can the flow direction on this type of globe valve be in either direction? The service is liquid oxygen with this valve located on the upstream side of the liquid oxygen vaporizers. There is a flow

I'm going through our specs on pad mounted oil filled transformers and came across the term filter press connection. Does anyone here know if the filter press is actually on the transformer oil compar

However I cannot figure out why the valve is not having any control. Is it possible the gas is cooling to the point of icing up around the plug, reducing flow?!? Or could the wrong plug type be causin

I am planning on machining a new Cylinder Head for my son's Pulling Garden Tractor over the winter. It is a single cylinder Kohler Flathead engine. Any thoughts on what is the best location for the Sp
