ABSTRACT:
The profile of the valve stop of a discharge valve conforms to the maximum bending stress or the maximum allowable fatigue stress whereby impact of the valve element with the valve stop occurs when the valve element has the least kinetic energy and highest potential energy such that the least possible kinetic energy is transferred to the valve stop.
