5) Since there is no pressure downstream of the regulator, the blocking valve model GIPS-FC will be in
the closed position, hence keep the bypass valve located on the side of the SSV pressed to
pressurize the span between the same and the pressure regulator.
6) Still pressing the SSV bypass valve, proceed by applying a light load onto the pilot regulation spring
in order to admit a small pressure downstream of the regulator valve, use a pressure gauge to
monitor this pressure rise and leave the pressure adjusted to a value at least 20% above the low set
point pressure of the SSV.
7) Once the SSV actuator is already pressurized, you may release the by-pass valve, and proceed by
resetting the SSV actuator.
8) Reset the shutter of the GIPS-FC security shut-off valve, using the reset lever.
9) Open the vent valve to 20%, check whether the pressure will continue at the preset value.
10) Using a 7/8” combination spanner turn the adjusting screw of the monitor valve clockwise to
increase the output pressure up to the desired value setpoint. Hence, only the monitor regulator is in
operation, and the system will behave as shown in the diagram below:
