Preventing backflow in your pneumatic system is a breeze with this non-return valve from Festo. When air flows into it in the right direction, its built-in float moves away from the opening and allows the air to pass through the component. A steel spring forces the float back again if the pressure inside the device drops too much. This prevents air from moving the other way, helping to keep your industrial processes flowing. Thanks to a wide operating temperature range between -10°C and +60°C, the valve's sure to beat the heat in tough industrial environments.

• Wrought aluminium alloy housing for resistance to corrosion and wear
• Screw-in mounting for simple and speedy setup
• Mountable in any position for flexible installation
• POM float is resistant to wear and moisture for a long service life
• Light weight of 9g minimises strain on your equipment

• Industrial sampling systems
• Nuclear energy
• Aircraft technology

This non-return valve has an operating pressure range between -0.95 and 0 bar, so it's just the thing for vacuum conditions.
