Abstract
A fluid control valve includes: a metallic body, including: a process surface with a central portion, a body clamping surface, and a body step between the central portion and the body clamping surface; at least one inlet orifice; at least one outlet orifice; an inlet port; and an outlet port; a metallic cap including a reference port, and a reference surface including: a cavity; a pressure pad; a cap clamping surface; and a cap step between the pressure pad and the cap clamping surface; and a metallic diaphragm between the body and the cap arranged such that, in response to a process pressure being higher than a reference pressure, a fluid flow path will be open from the inlet orifice to the outlet orifice, and in response to the reference pressure being higher than the process pressure, the flow path will be closed.
