Abstract

A pressure regulation tracking valve for maintaining the pressure of a gas relative to that of a process fluid includes means (15, 16), responsive to a change in the pressure of the process fluid, for changing the pressure of the gas by substantially the same amount. The valve further includes means (60, 80) for accommodating a pressure transfer medium for transferring the pressure of the process fluid to gas pressure changing means. In this way contact between said process fluid and said gas pressure changing means is avoided.
