If the pulmonary valve is open, which 2 valves should be closed?

This causes the pulmonary valve to close in the tricuspid valve to open. this lets blood flow right into the right ventricle that was returned to the right atrium from the body. when the left ventricle contracts, the right ventricle also contracts. this causes the pulmonary valve to open and the tricuspid valve to close.
