Pneumatic actuators are devices that convert compressed air or gas energy into mechanical motion (linear or rotary) to automate industrial processes.They use air pressure to move a piston or diaphragm, allowing for tasks such as clamping, lifting, pushing, and valve control. These actuators are preferred for their speed, safety in hazardous environments, and low maintenance.
Types of Pneumatic Actuators
Linear Actuators
DFPC
The Festo DFPC is a double-acting pneumatic linear actuator specifically optimized to automate process valves, such as gate, knife-gate, and pinch valves.
- Robust and corrosion-resistant tie-rod design
- Ideal for use in harsh ambient conditions
- Numerous configuration options
- Variants with fastening interface in accordance with ISO 5210 or ISO 15552 with extended tie rods
- Sustainable in production thanks to reduced use of materials
Linear actuator
DFPI
it’s a robust pneumatic unit that combines a cylinder, positioner, and measurement system into a single enclosure.
- Mounting interfaces to ISO 15552 on bearing and end caps
- Sturdy tie rod design
- Integrated air supply
- Optionally with integrated displacement encoder or fully integrated positioner
- IP65, IP67, IP69K, NEMA4
- To EU Explosion Protection Directive (ATEX)
Quarter-turn actuator
DFPD
The DFPD series features a rack and pinion combination with a constant torque characteristic across the entire swivel range. The quarter turn actuators DFPD are perfect for automating your butterfly valves, ball valves and dampers.
- Uniform torque characteristic across the entire rotation angle of 90° with the double-acting version
- Version with swivel angle 120°, 135°, 180° for the sizes 40, 120, 240, 480, double-acting
- Process valve connection to ISO 5211
- Mounting hole pattern to VDI/VDE 3845
- Sturdy, non-slip and easy-to-clean aluminium housing
- Long service life, low wear
- Sustainable thanks to extended life cycle and easier repairs
- Increased corrosion protection
Quarter turn actuator
DAPS
The Festo DAPS is a pneumatic quarter-turn actuator designed to rotate process valves (like ball or butterfly valves) exactly 90 degrees. It uses a Scotch Yoke mechanism to generate high torque precisely at the beginning of the stroke, making it ideal for overcoming the initial resistance (breakaway torque) of process valves.
- High breakaway torques
- Sustainable thanks to extended life cycle and easier repairs
- Flange hole pattern to ISO 5211
- Mounting hole pattern to VDI/VDE 3845
- Optionally with handwheel as a manual emergency override
- Corrosion-resistant version made from stainless steel
- To EU Explosion Protection Directive (ATEX)
- With safety functions.
Quarter turn actuator
DFPD-HD
The Festo DFPD-HD is a heavy-duty pneumatic quarter-turn actuator designed to provide high-torque control (up to 32,000 Nm) for industrial process valves like ball and butterfly valves.
- Ideal for applications with high torques up to max. 32,000 Nm
- Extremely modular for a variety of uses: configurable spring forces, a choice between right or left direction of rotation and mechanical or hydraulic manual override
- With safety functions
- Namur connection pattern to VDI/VDE 3845
- Variants to EU Explosion Protection Directive (ATEX)
