The DFS III

DFS III DFS III DFS III
The DFS III (9507-2108) is a dual valve controller that opens and closes motor
valves to maximize production of gas and oil wells. The The DFS III works off of time
and/or pressure. Using the optional transducers the controller incorporates a program
that allows the well to open and close by monitoring pressure. This application automatically
optimizes well performance by reacting to casing and/or tubing pressure for every cycle.
