Abstract
Improved valve seal and integrity systems and methods are disclosed. Pressure in an internal cavity of a valve may be monitored and stored to assist in determining whether one or more seals in the valve are leaking. Internal cavity temperature may also be recorded and monitored to assist in determining whether there are any valve seal leaks. Expected pressure corresponding to a detected internal cavity pressure (that may be determined by correlating temperature and known fluid properties) may be compared to detected internal cavity pressure to assist in determining the existence of valve leaks. Internal cavity pressures and pressure differentials over time may be used to determine remaining valve seal life, leak severity, and/or integrity of a check valve on the valve. Indications of seal life, leak severity, seal integrity, and/or check valve integrity may be displayed to an end user or otherwise provided to a database or computer.
