DFR

Model DFR rotary spring and diaphragm actuators are large diaphragm area actuators that allow for low-pressure operation. The spring provides fail safe positioning for a control valve on loss of pneumatic supply pressure. DFR actuators can be used to automate control valves for throttling or on/off control of liquids or gases.
