The following page which contains the Valves library in Simscape Fluids might help you,

Thank you for the answer. I have been to that page numberous times. Surprisingly, R2019b does not have the valve. I downloaded R2020a which has a normally closed sequence valve but not a normally oopen sequence valve which I also need.
