Product Information

Full details

The Festo VMEF Roller Lever Valve is a compact 5/2 monostable pneumatic valve for industrial automation. It offers precise flow control with a nominal flow rate of 750 l/min via G1/8 connections, operating efficiently from vacuum to 10 bar pressure. While its robust metal housing and piston slide technology ensure durability, users should note its mechanical actuation requirement and the specific G1/8 thread standard for connections.

Extended Product Information

FAQs

What is the thread size for pneumatic connections?

The valve uses G1/8 BSPP thread standard for its pneumatic connections.

What is the maximum operating pressure?

The maximum operating pressure for the Festo VMEF roller lever valve is 10 bar.

Can this valve be used for vacuum applications?

Yes, the valve can operate effectively in vacuum conditions down to -0.95 bar.

What type of actuation does this valve use?

This is a mechanically actuated valve, specifically using a roller lever for actuation.

What is the flow rate of this valve?

The valve has a standard nominal flow rate of 750 liters per minute (l/min).

What is the operating temperature range?

The valve can operate within a temperature range of -10°C to +60°C.

What material is the body made of?

The body material is an aluminium alloy, ensuring a durable construction.

Troubleshooting

Valve not actuating correctly

Verify that the roller lever is being fully depressed and that there are no obstructions. Check pneumatic connections and pressure.

Air leaks from connections

Tighten the G1/8 fittings. If leaks persist, inspect O-rings or seals and replace if necessary.

Reduced flow rate

Check the pneumatic supply for obstructions or pressure drops. Ensure internal valve components are free from debris.

Valve remains in the actuated state

Confirm the monostable function; the valve should return when actuation force is removed. If not, check for internal issues or external forces holding the lever.

Pros and Cons

Pros

  • Durable and reliable construction due to aluminium alloy body and piston slide technology.
  • Versatile operation across a broad pressure range, including vacuum applications.
  • Compact size allows for easy integration into space-constrained machinery.
  • High nominal flow rate ensures efficient pneumatic system performance.
  • Mechanical actuation provides a direct and responsive control mechanism.

Cons

  • Requires direct mechanical actuation, limiting remote control options without additional components.
  • Specific G1/8 thread standard may require adapter fittings if other thread sizes are in use.
  • Monostable design means it returns to its default state when the actuation force is removed.
  • Operating temperature range, while standard, may not suit extremely high or low temperature environments.
  • Primarily designed for pneumatic systems; not suitable for other fluid types.

Setup, Compatibility & Care

Setup:

  1. Ensure the air supply is clean and dry, free from contaminants that could affect valve operation.
  2. Connect pneumatic lines to the G1/8 ports, ensuring a secure seal to prevent leaks.
  3. Mount the valve securely in the desired location, ensuring the roller lever has a clear path for actuation.
  4. Connect control lines as per the system design.

Compatibility:

  • Compatible with standard pneumatic systems operating within the specified pressure range (-0.95 to 10 bar).
  • Utilizes G1/8 BSPP thread standard for pneumatic connections. Ensure compatibility with existing fittings or use appropriate adapters.
  • Designed for monostable operation, suitable for applications requiring a default return state.

Care:

  • Regularly inspect for air leaks around connections.
  • Keep the valve clean; wipe with a dry or slightly damp cloth. Avoid using solvents.
  • Periodically check the roller lever mechanism for smooth operation.
  • Ensure the pneumatic air supply is filtered and lubricated according to general pneumatic best practices, although this valve is designed for dry air too.
