A one way check valve is a kind of special check valve that includes a pipe having a fuel outflow port, a valve element attached in an openable and closable manner to the fuel outflow port of the pipe, the valve element being normally urged by a spring in a closing direction. The fundamentals of a particular type of valve relate to its sealing characteristics, which include in-line seat sealing when closed and where applicable stem sealing which should prevent potential leaks into the atmosphere. In the case of process systems handling hazardous fluids, harmful to both the atmosphere and personnel, stem sealing is considered to be of more importance.
