Product Description
The Festo HE series is a manually operated shut-off valve in a sturdy, reinforced PBT polymer design, offering reliable isolation of compressed air in pneumatic systems . Available with threaded ports, push-in connectors at both ends, or mixed configurations, this 2/2 or 3/2 bistable valve delivers high durability with soft sealing technology .
Key Features & Advantages:
Bistable Valve Function (2/2 or 3/2): Maintains its switched position without a permanent actuation force due to proven piston spool valve technology, providing stable open/closed states for energy-efficient operation .
Sturdy Reinforced PBT Polymer Housing: Made from high-strength PBT-reinforced material, offering excellent chemical resistance, high pressure tolerance (up to 10 bar), and corrosion resistance class CRC 2 for industrial environments .
Versatile Connection & Mounting Options: Available as thread/thread, push-in/push-in (QS-4 to QS-12), or mixed variants; supports direct in-line installation or panel mounting via through-holes .
High Flow Rate in Compact Form: Delivers flow rates ranging from 256 L/min (QS-6 variants) up to 840 L/min . Designed for wide operating temperatures from 0°C to 60°C and pressure ranges from -0.95 bar (vacuum) to 10 bar .
Cleanroom Compatible & Soft Sealing: Certified for Class 4 cleanrooms (ISO 14644-1) with NBR soft seals ensuring minimal leakage and reliable performance, supporting both lubricated and unlubricated compressed air .
