A standard fail‐close actuator assembly is first installed in the pipe run in the direction of flow.
The device is then connected to the HON
P095NG pilot, which in turn is also connected to the
regulating line’s inlet and outlet pressures. Together, the actuator assembly and the pilot
make up the monitor regulator unit.
Downstream of this setup, a fail‐open actuator assembly is installed with a HON
P095NG pilot
as well.
Together with the HON
P095NG pilot, this second actuator assembly makes up the active
regulator unit.
The outlet pressure is monitored by the upstream monitor regulator unit in addition to the
active regulator unit. The setpoint on the monitor regulator unit is set to a value higher than
the setpoint for the active regulator unit being controlled, which ensures that the monitor
regulator unit will normally be fully open. In the event of malfunction, the active regulator
unit opens according to the fail‐open principle. As soon as the set target value of the monitor
regulator unit has been reached, it starts regulating the outlet pressure.
