I just reviewed that ebay item and it appears to be a direct-lift, isolating diaphragm type valve which is absolutely appropriate for potable liquids as long as the diaphragm material is suitable (Buna-Nitrile, Viton or EPDM). Viton is the best choice for high temperatures but otherwise the...

Hey TJ, this is a diaphragm isolation valve and is suitable for propane as long as you don't exceed the maximum operating pressure differential (MOPD) of the valve with your propane tank. If you do, it will leak the propane right through the valve and may create an explosion in the presence of...

I know more about solenoid valves than I care to admit but don't worry about a valve getting hot to the touch. Most good quality manufacturers' valves are built to handle the heat under what is known as continuous duty (being powered on for extended periods of time). The cheaper valves from...

What you are refering to is the type of effect that has been used in determining flow as well. It's known as the coriolis effect. Measuring of differences in frequency as flow inside a vibrating tube changes can also easily be used to measure differences of frequency when SG changes. This...
