ABSTRACT:
A valve manifold for interfacing between a flowline control manifold and first and second pressure sensor units, the manifold having a monolithic body defining a mating surface for mating with the process control manifold and an instrument face for mating with the first and second pressure sensor units, the body having a peripheral wall with a first portion thereof being on the opposite side of the instrument face with respect to the mating face, the first portion of the peripheral wall forming an equalizing valve pocket surface for high and low pressure equalizing valve pockets carrying high and low pressure equalizing valves, respectively. High and low pressure fluid passageways extend from the mating surface to the equalizing valve pockets. The high pressure fluid passageway communicates with a high pressure plenum in the instrument face while the low pressure fluid passageway communicates with a low pressure plenum formed in the instrument face. An equalizing fluid passageway interconnects the high pressure and low pressure equalizing valve pockets. A gauge pressure passageway is connected to the high pressure fluid passageway and is in open communication with a second high pressure plenum formed in the instrument face. A block valve selectively controls flow through the gauge pressure passageway.
