Festo HGL Series Non-Return Check Valve 10 bar Max Operating Pressure, -10°C to 60°C Operating Temperature HGL-1/8-QS-6

Festo HGL-1/8-QS-6 Non-Return Check Valve is engineered for pneumatic systems requiring reliable, pressure-rated one-way flow control. Rated for a maximum operating pressure of 10 bar and operable from -10°C to 60°C, this valve supports a wide range of industrial and automation environments.

The valve features a robust construction using nickel-plated brass, brass, die cast zinc, anodised aluminium alloy, and sealing materials such as nitrile butadiene rubber (NBR). These materials ensure excellent corrosion resistance and durability in compressed air service. The media wetted components are carefully selected to balance sealing efficiency and longevity.

This model provides male/female inlet and outlet ports compliant with ISO 1179-1 and ISO 228-1 thread standards, ensuring straightforward integration with standard pneumatic fittings and push-in tubing connections. The polyoxymethylene releasing ring allows for maintenance operations, permitting removal and reinsertion of push-in fittings without body replacement.

Designed to meet RoHS compliance and the ISO 8573-1:2010 particulate purity standards, the valve guarantees environmental safety and air quality assurance for critical pneumatic applications.

Applications include compressed air distribution manifolds in industrial automation, preventing return flow on pneumatic actuators, use with control valves in electronic assembly air supplies, and bleed lines in mechanical press systems. The compact size and durable design make it suitable for installation where space and reliability are key.

Maximum operating pressure of 10 bar suitable for high-pressure pneumatic applications. Operational temperature range from -10°C to 60°C accommodates varied environmental conditions. Constructed from nickel-plated brass, brass, die cast zinc, aluminium alloy, and NBR for durability and corrosion resistance.

Features male/female inlet and outlet port genders compatible with ISO 1179-1 and ISO 228-1 thread standards. Compliant with ISO 8573-1 particulate standards and RoHS directives for quality and environmental safety. Ensures one-way flow to prevent backflow in pneumatic actuators and control valve circuits.

Polyoxymethylene releasing ring allows easy maintenance with push-in tubing fittings. Ideal for compressed air manifold distribution, electronic assembly air supplies, and bleed lines in mechanical presses.
