DAC Worldwide’s Constant-Differential Relay (Air), Control-Type Cutaway (273-850) is a detailed constant-differential relay cutaway that depicts a common constant pressure regulator and valve.
This common piece of pneumatic control hardware is found in manufacturing facilities, petro-chemical plants, refineries, and other similar industrial, commercial, and oil and gas applications. It is used within industrial process control systems in level control applications, such as bubbler assemblies.
The internal needle valve spring-actuated diaphragm maintains a constant internal differential pressure and constant volumetric flow rate. A full 1/4 cutaway unveils all internal construction details and its operating principles.
The cutaway includes a formed-steel mounting assembly, allowing for stand-alone display, bench-top mounting, or mounting on specialized DAC Worldwide mounting benches and support structures.
Through careful sectioning, the complete internal configuration of the device can be seen, while also allowing for disassembly for more compete inspection. All primary features have been retained and showcased using multiple colors.
