Sleeve valves can operate for long periods of time over a high differential pressure across the valve.

Some of the other mechanisms they described include a float chamber and an early differential pressure.

Failure is indicated by a decrease in the differential pressure.

Also if the fit is wrong then the differential pressure may be either too high or too low.

Therefore the range of differential pressure can become too large and compromise accuracy.

This creates a differential pressure forcing the heat and humidity toward the outside.

Absolute pressures (psia) must be used for gas rather than simply differential pressure.

The major integrity issues comes from the differential pressure across the casings due to the weight of brine on either side.

Isolators may operate at positive, negative, or ambient differential pressure.

Additionally, air enters the tube behind the free piston to create differential pressure.
