An example of this type of positioning control will include the mixing of hot and cold water, such that a specified downstream temperature requirement is achieved. Please see Max-Air 3-Way Tee Assemblies for specific examples. Other parameters which can be controlled are flow rates and pressure, as well as others. Many different types of models are offered, including pneumatic, electro-pneumatic, intrinsically safe, explosion proof, and Smart type positioners.
