Dyna-Flo DFC & DFO Linear Actuators
Large-diaphragm spring-and-diaphragm actuators with fail-safe positioning.
Large-diaphragm-area actuators for low-pressure operation. A spring provides fail-safe positioning on loss of pneumatic supply, where DFC fails closed and DFO fails open, to automate control valves for throttling or on/off service.
ACTS is Dyna-Flo Control Valve Services’s sole agent in Egypt, supplying the DFC & DFO Linear Actuators to oil & gas, petrochemical and power generation plants nationwide from our office in Sheikh Zayed City, Giza. Sizing and selection are handled by our own application engineers, with aftermarket support and technical services once the unit is in service.
