Valve Modeling Closures with K Factors
A closed valve would have an infinite K-factor. Since infinity is not a possible input, AFT Fathom uses the convention of K = -1 (negative one) to represent a closed valve.
This input is only valid when defining a valve transient while using the Fathom XTS Module. To represent a valve that is closed in steady state, use the valve Special Conditions in the Optional tab.
