FAQs
What is the primary function of the Festo EV-25-4?
The Festo EV-25-4 is designed for precise clamping of workpieces against a stop in automated industrial applications.
What are the main dimensions for clamping?
It offers a clamping area of Ø 25 mm and a stroke of 4 mm.
How is the module actuated?
It is a single-acting module, meaning it uses air pressure to clamp and a spring mechanism to retract when the air supply is released.
Can this module be used for gripping objects in mid-air?
No, this module is specifically designed for clamping against a fixed stop, not for general gripping or pick-and-place applications.
What type of air supply is required?
A clean, dry, and lubricated compressed air supply meeting ISO 8573-1 standards is recommended for optimal performance and longevity.
What is the benefit of the hermetically sealed design?
The hermetically sealed, diaphragm-fitted pressure chamber helps protect the internal mechanism from contaminants and ensures reliable operation.
What is the maximum stroke length?
The module has a fixed stroke length of 4 mm.
Troubleshooting
Module does not clamp when air is supplied.
Check the pneumatic connection for leaks. Ensure the air supply pressure is within the specified operating range. Verify that the control signal is correctly enabling air flow to the clamping port.
Module does not retract after air is released.
Ensure the air supply is completely vented from the clamping port. Check for internal obstructions or damage that might prevent the spring mechanism from returning the module.
Inconsistent clamping force.
Verify the air supply pressure is stable and within the recommended range. Inspect the clamping surface and the workpiece for any debris or irregularities that could affect seating.
Premature wear or damage.
Ensure the module is not being subjected to loads or environmental conditions beyond its specifications. Check for misalignment during operation or clamping against improperly positioned surfaces.
Pros and Cons
Pros
- Space-saving due to its compact and rodless design.
- Precise clamping with a controlled 4 mm stroke.
- Reliable operation with a hermetically sealed diaphragm.
- Suitable for automated processes needing secure workpiece holding.
Cons
- Requires a specific pneumatic supply for operation.
- Stroke length is fixed at 4 mm, limiting adjustability for some tasks.
- Primarily designed for clamping against a stop, may not suit all gripping applications.
Setup, Compatibility & Care
Setup: The EV-25-4 requires a clean, dry, and lubricated compressed air supply that meets ISO 8573-1 standards. Connect the pneumatic line to the appropriate port, ensuring a secure fit. The module is designed to be mounted via integrated through-holes or clamping surfaces. Ensure it is securely fixed to prevent vibration during operation. Actuation is achieved by supplying compressed air to the clamping port and venting it for retraction.
Compatibility: This module is compatible with standard industrial pneumatic control systems. Ensure your air supply pressure is within the specified operating range for the EV-25-4. It is designed to clamp against a rigid stop.
Care: Regular inspection of the pneumatic connections for leaks is recommended. Keep the area around the module clean to prevent debris from interfering with its operation. No user-serviceable parts are inside; maintenance typically involves checking pneumatic lines and ensuring the mounting is secure.
