First and the foremost thing it depends on the size of the pump. The main thing is that theoretically nothing will happen to the valve. But usually while the pump is running heat is developed due to the friction between the moving and static parts. This heat is usually dissipated to the fluid flowing through the pump. Hence on closing the discharge the heat dissipation is blocked and hence the temperature hikes up(churning effect of the pump impeller). This may lead to seal failure and impeller damage depending on how much time you are running the pump.
