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 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.
