difference between swing type check valve and non return valve? i need best answer... if swing valve will be opened when the fuel s reverse motion???
Non-return valve is another name for check valve. A swing check valve is just one type of check valve that uses a hinged gate to allow flow in only one direction. It operates sort of like a one-way fence gate, that you can open by pushing from one side, but you cannot open by pushing on the other side. Other types of check valves: Diaphragm, Ball, Lift, Duckbill. (:-o)
