Manual - Modular Valve Positioner (RS-232)
This operators manual for the Serial MVP covers installation, care, and RS-232 communication.

Hamilton Modular Valve Positioners are exceptionally easy to service and modify. It is very simple to remove and replace their snap-in valves with other configurations to achieve different fluid delivery with the same positioner unit, maximizing flexibility and value. You can choose from valves with two to eight ports that offer a total of 15 different flow paths. Valves are available with chemically inert PTFE and CTFE, or ceramic flow paths and can be customized per your requirements.
