Positioners

Max-Air Technology offers a full range of positioning equipment that is used to control the position of a valve (ball, butterfly, and globe) such that a given process will achieve certain desired flow parameters. 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.
