Product Information

Full details

The Festo Flat Cylinder DZH-25-25-PPV-A is designed for automation engineers and machine builders who require a compact, high-force pneumatic actuator for applications with limited space. Its key benefit is the space-saving oval piston design, which prevents rotation and allows for block mounting. A potential caveat is its specialized nature, requiring specific pneumatic control for optimal performance.

FAQs

What is the theoretical force of this cylinder?

At 6 bar (87 psi) of air pressure, the cylinder provides a theoretical advancing force of 295 N.

Can this cylinder be used without cushioning?

While it is designed with adjustable cushioning, it can be set to a minimum damping level. However, using some level of cushioning is recommended to protect the cylinder and connected components.

What is the primary advantage of the oval piston design?

The oval piston prevents the piston rod from rotating, which eliminates the need for external anti-rotation guides and allows for more compact, block-style mounting.

How do I mount this cylinder?

This cylinder is designed for block mounting due to its flat profile and oval piston. It can also be mounted using various accessories and mounting options compatible with its form factor and piston rod thread.

What is the maximum stroke length?

The stroke length for this specific model (DZH-25-25-PPV-A) is 25 mm.

Can I use this cylinder for applications requiring precise positioning?

Yes, the magnetic piston allows for integration with sensors to provide feedback on the cylinder's position, enabling precise control in automated systems.

What type of compressed air should I use?

It requires clean, dry compressed air that meets ISO 8573-1 standards. Using filtered air is highly recommended to ensure longevity and performance.

Troubleshooting

Cylinder does not extend or retract.

Verify air supply pressure and connection to both ports. Check for any obstructions or binding in the mechanism it's connected to. Ensure control valve is functioning correctly.

Cylinder retracts/extends too quickly or slams at the end of stroke.

Adjust the pneumatic cushioning screws. Turn clockwise to increase damping (slow down) or counter-clockwise to decrease damping (speed up). Make small adjustments incrementally.

Piston rod drifts or rotates.

The oval piston design inherently prevents rotation. If rotation is observed, ensure the cylinder is not subjected to external torsional forces or that the connected load is not causing binding. Confirm correct mounting.

No signal from magnetic piston sensor.

Ensure the sensor is correctly positioned and compatible with the magnetic piston. Check sensor wiring and power supply. Verify the sensor is within its sensing range of the piston.

Pros and Cons

Pros

  • Extremely compact design saves valuable space.
  • Integrated anti-rotation prevents the need for external guides.
  • Adjustable cushioning provides smooth operation and extends cylinder life.
  • Magnetic piston simplifies integration with sensors for automation.
  • Durable construction suitable for industrial environments.

Cons

  • Limited stroke length may not be suitable for all applications.
  • Requires specific pneumatic control for adjustable cushioning.
  • Theoretical force rating is dependent on optimal air pressure.
  • Specialized design may require specific mounting adapters.

Setup, Compatibility & Care

Setup:

  1. Ensure the cylinder is mounted securely using appropriate brackets that align with its form factor.
  2. Connect compressed air lines to the designated ports, ensuring correct port identification for double-acting function.
  3. Install proximity sensors on the cylinder barrel if position sensing is required, aligning them with the magnetic piston's travel.
  4. Adjust the pneumatic cushioning screws located at each end of the cylinder. For initial setup, turn them fully clockwise, then back out 1-2 turns. Fine-tune based on observed end-of-stroke behavior.

Compatibility:

  • Requires a clean, dry compressed air supply meeting ISO 8573-1 standards.
  • Compatible with standard pneumatic control valves.
  • Mounting options and piston rod thread allow integration with various end-effectors.

Care:

  • Regularly inspect air connections for leaks.
  • Periodically check and adjust cushioning if operating conditions change.
  • Ensure the air supply is filtered to prevent internal contamination.
  • Avoid exceeding the maximum operating pressure or temperature limits.
