Festo 5/2 Bistable Air Solenoid Valve - G3/8

It is a 5/2 bistable pneumatic solenoid valve with electrical actuation and G3/8 pneumatic connections.

The nominal flow rate is 2300 l/min.

Yes, a 5/2 bistable valve can control both double-acting and single-acting actuators. For single-acting actuators, one of the output ports can be capped if not used, or the exhaust port can be utilized based on the actuator's design.

No, this valve is designed to operate reliably with either lubricated or unlubricated compressed air, provided the air quality meets the relevant ISO standards.

This valve is compatible with Festo's VTUS manifold systems. Ensure the manifold base has the correct porting and mounting pattern for the VUVS series valves.

Bistable means the valve has two stable positions. It will remain in the last actuated position even if the electrical control signal is removed. A signal of opposite polarity or a different control input is required to switch it to the other position.

G3/8 is the standardized thread size for the pneumatic ports, ensuring compatibility with standard fittings and tubing used in industrial pneumatic systems.

Check the electrical supply to the solenoid. Verify voltage and current match the valve's specifications. Ensure wiring is correct and secure. Check for any physical obstructions preventing the spool from moving.

Verify the nominal flow rate (2300 l/min) is sufficient for the connected actuator. Check for restrictions or blockages in the pneumatic lines or exhaust ports. Ensure the air supply pressure is adequate.

Ensure the valve is correctly seated on the manifold or that tubing connections are properly sealed. Check for damage to internal seals, which may require valve replacement.

This is the normal behavior of a bistable valve. If a specific state is required upon power restoration, additional logic or a different valve type (e.g., monostable) may be necessary.
