... Abstract The check valve is one of the most important devices for safety protection of the piping system in thermal and nuclear power plants. As the key component of the check valve, the valve disc accounts for a major effect on the flow characteristics especially during the opening and closing...

... Abstract Experimental investigations of dynamic characteristics of the check valve are a contribution work to provide boundary condition to check valve mathematical simulation. The closure process of the check valve was tested. The changing processes of inlet and outlet pressure were performed...
