Amico Dome Loaded Manifold CSA - Manual (Page 8)

8 Amico Pipeline
DUAL LINE REGULATOR
On every Amico Automatic Gas Manifold the line regulator is capable
of maintaining a constant dynamic delivery of pressure at the maximum
designed flow rate of the system. For Oxygen, Nitrous Oxide, Medical Air and
Carbon Dioxide service, the line regulators are factory preset at 55 PSI and for
Nitrogen it’s 170 PSI.
PRESSURE RELIEF VALVE
Pressure relief valves are installed downstream of all pressure regulators and
are set at no more than 50% above the setting of the pressure regulator.
Relief valves are capable of fully relieving the pressure at the set point. All
pressure relief valves in the manifold have piping connections to allow for
connection of a vent line to the outside of the facility.
PILOT REGULATOR
A single stage, diaphragm-type, relieving regulator is used to limit the
amount of pressure provided to the domes of the bank regulator. It is used
only on Nitrogen manifolds and manifolds with more than 100 PSI delivery
pressure.
SOLENOID VALVE
A 12 VDC solenoid assembly used to direct dome bias pressure to one of the
bank regulators. As dome bias pressure is directed to one of the bank regulators,
dome pressure of the other bank regulator is vented through an exhaust in the
solenoid valve.
Quarter-turn ball valves are provided upstream and downstream of each line
regulator. These valves allow for removal and servicing of one of the line
regulators while the other is in use. All four ball valves are normally in the
open position.
