1. A pressure regulator comprising:
a valve body module including a valve body housing block retaining a poppet and a seat seal;
a loading module including a loading block retaining a loading element configured to apply a load force to a sensing member disposed between the loading element and the poppet;
a piston module including a piston adapter block secured to the valve body housing block and retaining the sensing member in engagement with the poppet, wherein the sensing member comprises a piston and the piston adapter block includes a piston bore retaining a stepped fluid driven portion of the piston; and
a venting module including a venting adapter block secured between the piston adapter block and the loading block and defining a vent port in fluid communication with a vent passage in the sensing member;
wherein the valve body housing block and the piston adapter block each include a uniformly sized first assembly interface, and the piston adapter block and the venting adapter block each include a uniformly sized second assembly interface in mating and sealing engagement with the first assembly interface of the adjacent one of the valve body housing block and the piston adapter block, such that the valve body housing block is configured for assembly directly to the venting adapter block after removing the piston module from between the valve body housing block and the venting adapter block.
