Festo Piloted check valve, HGL-3/8-B (530032)

This piloted check valve is designed for controlled one-way airflow with pilot-actuated release in pneumatic systems. It is used where directional control and pressure-based piloting are required and supports both male and female port connections. Built from a combination of metal and polymer materials, it operates reliably within standard industrial temperature and pressure ranges.

Features & Benefits

• Maximum operating pressure 10 bar provides high-pressure capability
• Minimum operating pressure 0.5 bar ensures reliable actuation threshold
• Operating temperature range -10 °C to 60 °C supports varied environments
• NBR sealing material offers chemical and wear resistance
• Anodised aluminium and plated brass bodies reduce corrosion
• Available with male or female ports for installation flexibility

Applications

• Suitable for pneumatic circuits requiring directional locking with pilot release
• Ideal for automated valve manifolds in assembly-plant Air systems
• Used for preventing backflow in compressed-Air distribution lines
• Suitable for machine tools where pressure-dependent release is needed
• Used for control subsystems in automation involving pneumatic actuation
