Festo GRA Series Flow Valve, 10 Bar Maximum Operating Pressure, Die Cast Zinc - GRA-1/4-B, Numeric Part Number: 6509

This flow valve regulates fluid flow in pneumatic and industrial systems, providing Compact control for machinery and process equipment. It is intended for non-hazardous environments and offers a balance of operational range and robustness for use in automation, electrical and mechanical installations.

Features & Benefits

• Die cast zinc body provides Durable corrosion resistance and mechanical robustness
• Maximum operating pressure 10 bar enables high-pressure process control
• Temperature capability from -20°C to +75°C supports varied ambient conditions
• Minimum operating pressure 0.1 bar allows flow control at low system pressures
• Compact construction simplifies integration into confined assemblies

Applications

• Suitable for flow rate control in pneumatic actuators and valves
• Ideal for integration into assembly-line automation systems
• Used with control panels in electrical and electronics testing rigs
• Can be used for regulating supply to machine tools and mechanical fixtures

What materials are used in the valve construction and why does that matter?

The main body is MADE from die-cast zinc, chosen for its strength-to-weight ratio and resistance to moderate mechanical wear, aiding longevity in industrial settings.

What environmental conditions can it operate in reliably?

It functions across a temperature span from -20°C up to +75°C, making it suitable for workshops, factory floors and indoor plant rooms that experience seasonal and process-related temperature variation.

How does the valve perform at low supply pressures?

It remains functional down to a minimum pressure of 0.1 bar, enabling controlled flow even when upstream pressure is limited.

Is this valve appropriate for use in classified hazardous locations?

It is intended for non-hazardous areas and does not carry hazardous-area certification, so it should not be installed in classified zones.
