4-4.3 Systems Using Discharge Delays
Discharge delays prevent a system from discharging until a specified time has expired.
Discharge delay systems use nitrogen from a nitrogen pilot cylinder for activation of the
cylinder valves. Use an electric control head to open the valve on the pilot cylinder. The
nitrogen then travels to the discharge delay. The discharge delay prevents the nitrogen from
pressurizing the activation line until after the delay has expired. The discharge delay can be
bypassed by using a manual lever operated control head on the discharge delay. Figure 4-4
illustrates a system with a discharge delay.
