Five valve manifold for use with a pressure sensing apparatus
First Claim
1. A five valve manifold for use with a pressure sensing apparatus, said manifold comprising in combination:
- (a) an integral body having a first face section, a second face section, generally parallel with the first face section; and
a peripheral wall sectional, the distance between the first and second face sections being smaller than at least one of the width and the length of the second face section;
(b) a passage system disposed within said body and including a plurality of mutually intercommunicating passages;
(c) said passage system including;
(i) a high pressure inlet for the process flow;
(ii) a high pressure outlet for the instrument flow;
(iii) a low pressure inlet for the process flow;
(iv) a low pressure outlet for the instrument flow;
(v) a vent outlet;
(d) said high and low pressure inlets being disposed in said first face section, said high and low pressure outlets being disposed in said second face section;
(e) said second face section being sealingly compatible with respect to an inlet portion of a housing of a respective pressure sensing apparatus to provide a hermetical sealing engagement therewith, while communicating said high and low pressure outlets with respective inlet portions of the pressure sensing apparatus;
(f) selectively operable valves, each having a valve stem portion disposed inside the body and carrying a valve member, and an actuating stem portion projecting outwardly from the peripheral wall portion of the body;
(g) said actuating stem portions being spaced from each other about the periphery of the body and being all located within a space limited by a first reference plane generally coincident with said first face section, and by a second reference plane generally coincident with said second face section; and
(h) a plurality of mounting bolt passages disposed around the periphery of the body, extending each from the first to the second face section and generally perpendicular to the face sections.

Abstract
A five valve manifold for use with a pressure sensing apparatus is disclosed. It has an integral body having a first face, a second face, parallel with the first face. A peripheral wall section, spans the distance between the first and second face sections. The distance is smaller than at least one of the width and the length of the second face section. A passage system within said body and includes a plurality of mutually intercommunicating passages extending from one said face to the other. A set of five valves operates selective opening and closing of the passages. The centers of the instrument outlets at one face are suited to new type of "smart" pressure transmitters, while the inlet ports at the other correspond to the usual spacing used in the industry. The invention eliminates the use of a so-called parallel flange used by the manufacturers of pressure transmitters to accommodate the difference in the centers of connecting ports of the instrument from that previously used by the industry.
