At ambient temperature the chemical resistance chart shows my process media as OK with the valve and seal materials yet Im still getting seal leaks. Whats wrong?
Fluid inside the valve can reach temperatures above ambient because of the operating temperature of the coil. The hot coil heats the process media which can raise its temperature considerably. Remember, that the fluids that may not effect the valve seals at ambient temperature, can cause problems at higher temperatures.
