Festo VBNF-CBA-Q6-Q6, Pneumatic Check Valve

The Festo VBNF-CBA-Q6-Q6 is a pneumatic check valve that controls airflow in one direction while blocking reverse flow. It is typically used in compressed air systems where backflow can cause pressure loss, instability, or component damage. This valve does one job and does it reliably, keeping air moving the way it should. It fits cleanly into standard pneumatic lines and runs quietly in the background, requiring no adjustment or regular attention.

Unparalleled Benefits of Choosing the Festo VBNF Series Check Valve

This check valve allows compressed air to pass freely in one direction and automatically closes when the flow tries to reverse. This helps maintain pressure in specific sections of a circuit and prevents unwanted air discharge.

• Cylinders need to hold position.
• Pressure must be maintained after shutdown.
• Backflow could affect system timing or safety.
• Push-in fittings for fast tube connection.
• Compact body for space-limited systems.
• No tools needed for standard installation.

Solid Check Valve for Controlled Airflow

The VBNF-CBA-Q6-Q6 uses push-in connections at both ends for 6 mm tubing. Installation is quick and clean, even in tight control cabinets or compact machine layouts.

Applications Across Different Fields

This check valve is typically found in:

• Pneumatic automation systems
• Industrial machinery and production lines
• Control panels with multiple air circuits
• Systems using cylinders, grippers, or air actuators
