Dynaflo Model 4000/4010 Pressure Controller
The 4000 and 4010 Series pneumatic pressure controllers are manufactured to a high level of quality specifications to ensure superior performance and customer satisfaction. The pressure controllers are used in all kinds of demanding applications, including oil and gas production and chemical process industries. The pressure controllers sense the process pressure using a Bourdon tube-sensing element. The process pressure is then compared to an operator-adjusted set point, which in turn modulates the controller output. The controller output is then connected to a final control element that changes the process pressure.

Dynaflo Model 5000 Level Controller
The Dyna-Flo 5000 series level controllers are implemented for use in many demanding applications, including oil and gas production and chemical process industries. Typical applications would be on gas scrubbers and separators, where liquid level control is required as well as natural gas compressors and process control applications
