The DFC and DFO Series linear output actuator's
large diaphragm area
allows for low-pressure operation, and the spring provides fail
positioning of a control valve on loss of pneumatic supply. Model
actuators are fail closed and Model DFO actuators are fail open.
The Model DFR can accept a splined shaft or square stub,
making for easy
automation of valves, louvers, dampers or any other quarter turn
application. A CNC machined steel lever offers a higher factor of
a cast steel lever which makes DFR actuators stronger than most
competitors. The rigid structure is also a stable base for accurate

The Model DFRPThe Model DFRP pneumatic piston rotary actuator is used in all kinds of demanding applications involving splined shaft rotary control valves, such as the Dyna-Flo 590 and 570 Series valves. The linkage of this actuator can be positioned for either push-down-to-open or push-down-to-close action.
The Model DFN is a bracket-mounted, direct acting,
spring and diaphragm
actuator. Common applications include operation of butterfly valves,
and louvers. The steel welded design provides necessary stability
reliability under extreme working conditions.
Dyna-Flo D-Force actuator is a rugged dual piston scotch
actuator designed specifically for automation of quarter turn valves.
The torque curve closely matches the requirements of valves that
have a lower running torque with higher breakout and re-seat torques.
design also makes it a good choice for almost any application where
is limited. Check out the features for more details!
Dyna-Flo Large D-Force actuator is a rugged single piston
(dual piston for double acting) scotch yoke actuator designed specifically
for automation of quarter turn valves. These actuators transform
linear piston movement into a 90O rotating movement for ideal break
and run torque. Available in a wide range of sizes for use with
a variety of pressure ratings, the D-Force actuator line is a reliable
choice for applications requiring a piston rotary actuator.
