    摘要： 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.

    摘要： A valve assembly is adjustable in three independent ways allowing it to provide a variable input volume. The valve assembly has a base and an entrance plate. An outer guide, an inner guide and a shaft, each with a passage, are held together and the shaft is rotatable between the guides. The valve is open when the passages of the inner guide plate and shaft are aligned and closed when the passages are not aligned. The shaft RPM determines how many times per minute the valve opens. The open/closed ratio of the valve assembly determines how long the valve is open during each half revolution. The location of the shaft up or down in relationship to the inner guide determines what percentage of possible flow passes through the valve during each half revolution. The valve assembly can be used with either a gas or liquid medium.

    摘要： A high pressure plug valve includes a valve body having an annular inner surface with a taper having a first taper direction and an annular body saver having an outer surface with a taper having a second taper direction opposite the first taper direction. The outer surface of the annular body saver adapted to interface with the annular inner surface of the valve body with a tapered interference fit.
