Figure 2-3. QuickTrip Steady State Leakage (70 °C hydraulic oil)
The figures above show the maximum expected steady
flow through the QuickTrip assembly during normal operation. It is
important to size the trip system orifice such that the trip header
pressure does not fall below the system trip pressure when channel A
is open (maximum leakage).
