1. A process control system comprising:
a fluidic line having a longitudinal axis and comprising a fluidic connection having an axis angled relative to the longitudinal axis of the fluidic line;
a primary block valve having an inlet port and an outlet port, the inlet port coupled to the fluidic connection and being aligned the axis of the fluidic connection; and
a monoflange comprising:
a male portion aligned with the axis of the fluidic connection, the male portion forming an inlet port and comprising an external threaded surface;
an outlet port aligned with the axis of the fluidic connection;
a flanged interface surrounding the outlet port of the monoflange and being aligned with the axis of the fluidic connection;
a bleed port;
a bleed valve having a valve seat disposed within and integral with a body of the monoflange and adapted to control fluid flow from the bleed port, the bleed valve having a bonnet flange mounted directly to the monoflange by a first threaded connection; and
a secondary block valve having a valve seat disposed within and integral with the body of the monoflange and adapted to control fluid flow from the outlet port of the monoflange, the secondary block valve having a bonnet flange mounted directly to the monoflange via a second threaded connection;
wherein the external threaded surface of the male portion threadably engages the outlet port of the primary block valve; and
further wherein the bleed valve and the secondary block valve are oriented perpendicular to the axis of the fluidic connection.
