The DFC and DFO Series linear output actuator's
large diaphragm area
allows for low-pressure operation, and the spring provides fail
safe
positioning of a control valve on loss of pneumatic supply. Model
DFC
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
safety than
a cast steel lever which makes DFR actuators stronger than most
competitors. The rigid structure is also a stable base for accurate
and
repeatable performance.

The Model DFN is a bracket-mounted, direct acting,
spring and diaphragm
actuator. Common applications include operation of butterfly valves,
chokes,
and louvers. The steel welded design provides necessary stability
and
reliability under extreme working conditions.
The
Dyna-Flo D-Force actuator is a rugged dual piston scotch
yoke
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.
The compact
design also makes it a good choice for almost any application where
space
is limited. Check out the features for more details!
