ABSTRACT:
A pressure control arrangement for a fluid line in a system, particularly a pressure swing adsorption system, wherein, in the event of a valve or control system malfunction, there is a risk of the fluid line being subject to an overpressure in an excess of its maximum design pressure, has a normally open valve, a flow restricting member, and a pressure sensor disposed in the fluid line.
The pressure sensor is disposed upstream of the flow restricting member and arranged to sense the pressure in the line and to actuate the valve to close the line in the event of the sensed pressure exceeding a predetermined limit. The predetermined limit is above the normal operating pressure range of the fluid line but below the maximum overpressure to which there is a risk of the line being subject, and that portion of the fluid line upstream of the flow restricting member is constructed to have a maximum design pressure at least equal to the maximum overpressure.
