Claim 0:
1. A system comprising:
a valve comprising: (i) a body having a cylindrical cavity, (ii) a movable member having a first portion with a first diameter and a second portion with a second diameter smaller than the first diameter, wherein the movable member is movable in the cylindrical cavity of the body, and wherein the first portion divides the cylindrical cavity into a first chamber and a second chamber, (iii) a first seal positioned to form a seal between the first portion and the body, (iv) a second seal positioned to form a respective seal between the second portion and the body, (v) a first pressure sensor configured to measure pressure level in the first chamber during movement of the movable member to generate a first pressure versus time curve, and (vi) a second pressure sensor configured to measure pressure level in the second chamber during the movement of the movable member to generate a second pressure versus time curve; and
a controller performing operations comprising:
comparing the first pressure versus time curve and the second pressure versus time curve to a baseline pressure versus time curve,
determining, based on the comparing, whether the first seal or the second seal has degraded during use of the valve, and
providing an indication of which of the first seal or the second seal has degraded.
