Festo Series H Check Valve, 0.4-12 Bar Operating Pressure, Anodised Wrought Aluminium Alloy Housing - H-1/4-B

This check valve prevents reverse flow in pneumatic systems and is intended for industrial air control applications. It is constructed with a corrosion-resistant anodised wrought aluminium alloy housing and is designed to operate across a wide pressure band and typical workshop temperature ranges.

Features and Benefits:

• Operates from 0.4-12 bar for versatile pressure management
• Functional to 60°C supporting higher-temperature process lines
• Withstands down to -10°C for cold-environment operation
• Complies with RoHS to reduce restricted-substance usage
• Lightweight aluminium housing enabling easier mounting

Applications

• Suitable for pneumatic control circuits in manufacturing plants
• Ideal for compressed air distribution and line protection
• Used with actuators to prevent backflow during shut-off
• Can be used for pressure-hold functions in assembly tooling

What operating pressures can I expect for stable performance?

The valve functions across a minimum of 0.4 bar up to a maximum of 12 bar, providing consistent one-way flow control within that range.

How does the material choice affect installation and maintenance?

The anodised wrought aluminium alloy housing offers corrosion resistance while remaining light, simplifying placement and reducing mechanical support needs.

Are there environmental temperature limits for reliable operation?

It is rated to operate down to -10°C and up to 60°C, allowing use in typical cold stores and warm production zones without thermal derating.

Does the unit meet any restricted-substance standards?

It is RoHS compliant, indicating it adheres to restrictions on certain hazardous materials in electrical and electronic equipment.
