The Festo VMEF-K-M52-M-G18 roller lever valve is designed for automation engineers and technicians needing a compact, reliable 5/2 monostable pneumatic control solution. Its key benefit is precise mechanical actuation in space-constrained applications, though its mechanical nature requires direct activation for operation. This valve features a durable aluminium alloy housing, a 750 l/min nominal flow rate, and suitability for both vacuum and positive pressure environments.

This valve is ideal for pneumatic control in automation, particularly in applications requiring direct mechanical actuation, such as conveyor diverters, clamping mechanisms, or as a component in larger, manually controlled systems.
A monostable valve returns to its default position when the actuating force is removed (like this VMEF valve). A bistable valve remains in its last actuated position until a reverse force is applied.
It is designed for standard compressed air. Using aggressive chemicals or liquids in the air supply is not recommended and may damage the valve.
The maximum operating pressure for this valve is 10 bar.
The valve features G1/8 ports, which adhere to the BSPP (British Standard Pipe Parallel) thread standard.
The valve is actuated mechanically via a roller lever. Applying force to the roller causes the valve to switch states.
The valve can operate reliably within a temperature range of -10°C to +60°C.
Verify sufficient actuation force is applied to the roller lever. Check pneumatic supply pressure and ensure it is within the -0.95 to 10 bar range. Confirm air lines are correctly connected and not kinked.
Inspect all pneumatic connections for tightness. Check the valve body for any visible damage. Ensure seals are intact and the valve is not operating outside its specified pressure range.
Check for restrictions in the pneumatic lines or excessive tubing length. Ensure the air supply pressure is adequate. Clean any debris from the valve's internal mechanism if accessible and safe to do so.
Ensure the actuating lever is returning freely when the external force is removed. Check for foreign particles within the valve mechanism. Verify that the monostable return spring is functional.
Setup: Mount the valve securely in its intended position, ensuring the roller lever is free to move and aligns with the actuating mechanism. Connect pneumatic lines to the G1/8 ports, ensuring proper thread sealing. Use compressed air filtered to at least 40 µm. For optimal performance, ensure the air supply meets the specified pressure range of -0.95 to 10 bar.
Compatibility: The valve uses standard G1/8 (BSPP) thread connections, making it compatible with a wide range of pneumatic fittings and tubing. It is designed for 5/2 monostable pneumatic control circuits.
Care: Regularly inspect the valve for any signs of damage or wear. Ensure the actuating roller and lever mechanism are clean and free from debris. If the valve performance degrades, check pneumatic lines for leaks and ensure the air supply is clean and dry. Avoid using abrasive cleaners; a slightly damp cloth is sufficient for external cleaning.
