Festo VMEF Series Pneumatic Valve - 3/2 Monostable Roller Lever - G1/8

Its primary advantage is its compact size (20mm width) combined with a high flow rate (750 l/min), making it ideal for space-constrained applications requiring reliable pneumatic control.

No, this is a mechanically actuated roller lever valve. It requires direct physical contact to operate, not an electrical signal.

The valve features G1/8 ports with a BSPP (British Standard Pipe Parallel) thread standard.

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

Yes, it can operate in vacuum applications down to -0.95 bar, as well as positive pressure up to 10 bar.

Monostable means the valve has one stable position (the default state when not actuated) and returns to this position automatically once the actuation force is removed.

The body is constructed from a durable aluminium alloy.

Ensure the roller lever is not obstructed and has sufficient travel. Verify that the actuating cam or component is properly aligned and making full contact.

Check all pneumatic connections for leaks. Ensure the supply pressure is within the -0.95 to 10 bar range. Inspect internal valve components for contamination (requires disassembly by qualified personnel).

Verify that there are no external forces holding the lever. Ensure the internal spring mechanism is not damaged or obstructed. Check that the system pressure is not inadvertently holding the valve in the actuated state.

Ensure threads are clean and properly sealed using appropriate thread sealant tape or paste. Verify that the mating component's threads are not damaged.
