An instrument valve manifold 10, 210 interfaces between a flowline control manifold CM and one or more pressure transmitter units T1, T2. The instrument valve manifold includes a monolithic body 32,232 that defines a mating surface 34,234 having a low pressure port 52, 252 and a high pressure port 54, 254, a low pressure plenum 58, 258 and a high pressure plenum 60,260, and at least one equalizing valve pocket 96, 296 for receiving an equalizing valve 100, 300. Fluid passageways in the body 32, 232 extend from the low pressure input port to the low pressure plenum and from the high pressure input port to the high pressure plenum. The instrument valve manifold reduces the size and weight of components connected to the control manifold, reduces the moment arm of the combined weight of the instrument valve manifold and the transmitter on the control manifold, and distributes the weight substantially equally about the plane of symmetry 30 of the control manifold.
