Festo Piloted check valve, HGL-1/8-QS-6 (530040)

This non-return valve provides one-way flow control for compressed Air installations, preventing backflow in pneumatic systems. It is intended for use where compact, pressure-rated check valves are required, offering compatibility with threaded inlet and outlet connections as well as push-in tubing interfaces for ease of integration into machinery and control circuits.

Features & Benefits

• Maximum operating pressure 10 bar for high-pressure applications
• Operates from 0.5 bar for reliable low-pressure function
• Temperature performance from -10°C to 60°C for varied environments
• Constructed from nickel-plated brass and aluminium for corrosion resistance
• Conforms to ISO 8573-1 particulate standards for Air quality assurance

Applications

• Suitable for compressed Air distribution manifolds in automation
• Ideal for return-flow prevention on pneumatic actuators
• Used with control valves in Electronic Assembly Air supplies
• Can be used for bleed lines in mechanical press systems
