Product Description
The Festo HAB series manual override is an exhaust component specifically designed for use with HGL check valves, enabling manual release of trapped air from pneumatic systems or cylinders . This valve element allows controlled venting of locked-in pressure, facilitating maintenance and troubleshooting without requiring electrical actuation, and is rated for ATEX explosive atmospheres.

Key Features & Advantages:

• Exhaust Valve Function: Operates as a dedicated venting element to manually release compressed air locked in cylinders or pneumatic circuits by the HGL check valve, providing a safe method for pressure relief during maintenance .

• ATEX Explosion Protection: Certified for use in potentially explosive gas and dust atmospheres (Zones 1, 2, 21, 22), making it suitable for hazardous industrial environments in chemical, pharmaceutical, and petrochemical applications .

• Moderate Corrosion Resistance: Rated with Corrosion Resistance Class (CRC) 2, providing reliable protection against moderate corrosion stress for long-lasting performance in humid industrial environments .

• LABS (PWIS) Conformity: Complies with VDMA24364-B1/B2-L standards for paint-wetting impairment substances, making this component suitable for paint shop environments and applications sensitive to paint defects .

• Multiple Connection Sizes: Available in G1/8 (184585), G1/4, and G1/2 (184588) thread sizes to accommodate different pneumatic system requirements .

• Wide Operating Temperature Range: Operates reliably from -20°C to 80°C for both ambient and media temperatures, ensuring consistent performance across extreme industrial conditions .

• Durable Anodized Aluminum Construction: Manufactured from wrought aluminum alloy with anodized finish, providing excellent corrosion protection and mechanical durability .

• Screw-In Mounting Type: Designed for simple screw-in installation with 8 Nm maximum tightening torque, enabling secure attachment to HGL check valves .

• Oiled or Unlubricated Operation: Allows operation with both lubricated and unlubricated compressed air, though initial lubrication requires continued lubrication for ongoing operation .

• Flexible Mounting Position: Allows any mounting position, providing installation flexibility for complex pneumatic system configurations .

• Compact and Lightweight: HAB-1/2 model weighs only 35 g, adding minimal mass while providing critical exhaust functionality .

• RoHS Compliant: Manufactured without restricted hazardous substances, meeting environmental compliance standards .
