FEA on Multi Door Check valve / Recoil type multi door check valve

FEA on Multi Door Check valve / Recoil type multi door check valve

FEA on Multi Door Check valve / Recoil type multi door check valve

I have been trying to simulate the hydro-static seat pressure test for a multi door check valve. I have attached the sample product
line diagram image(IMAGE SOURCE-GOOGLE). You can also search the term and look at the product easily for clarity.
ACTUAL TEST SCENARIO: The pressure is applied from the opposite side of the flow direction with all the doors closed. As it is a metal seated valve, the contact surface between door and diaphragm( the large circular plate on which door sits in closed position) is metal. Door seal material is Bronze LTB2 and diaphragm seat ring is integral nickel weld overlay. So please kindly suggest a methodology to simulate this condition in Ansys Mechanical Pro - Static structural analysis only.
