A. Check its opening and reseating pressure. Through the hole on PQ-II deflation valve,
its pressure value can be adjusted by using a screw driver. Pressure value will be
adjusted to a higher value if the screwdriver turns the adjusting nut clockwise or to a
lower value counter-clockwise.
B. If the adjustment failed, the valve-core, the spring or even the whole set of non-
return & pressure-limited valve should be replaced.
