DFC and DFO Actuators
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.
Features:
- Open Yoke – Open Valve Stem
- Steel & Thick Section Cast Iron
- Versatile mounting options for positioners and limit switches
- Throttling and On/Off Control Capabilities

DFLP Actuators
The Model DFLP pneumatic piston actuator is designed for high powered demanding applications. Multiple mounting configurations and actions can easily be achieved due to the universal design.
Features:
- High reliability
- Innovative cylinder design
- Open yoke – open valve stem
- Versatile mounting options for instrumentation

DFR Actuators
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.
Features:
- Low Pressure Diaphragm
- Fail-Safe Spring
- Splined Connection
- Offers board range of torque output
- Compatible with a wide variety of Instrumentation when combined with a Model 560 control valve

DFRP Actuators
The 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.
Features:
- High reliability
- Innovative cylinder design
- Open yoke – open valve stem
- Versatile mounting options for intrumentation

DFN Actuators
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.
Features:
- Actuator may be installed in any position
- Deep casings provide up to 4-1/8″ (105 mm) of travel for a size 156 actuator
- Square Yoke provides a versatile mounting surface for accessories
- Four holes in the actuator base permit bracket or plate mounting

D-Force Actuators
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!
Features:
- Available in a double acting (DDA) and spring return (DSR) configuration
- Features externally adjustable travel stops
- D-Force actuators offer a compact design
- Low and high temperature configurations available
- D-Force actuators are constructed using one piece splined drive shafts

D-Force Larger Size Actuators
The 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.
Features:
- On-Shelf Availability
- Rugged Construction
- Ease of Installation
- Longer Service Life
