Product Description
The Festo QH-QS and QHS-QS series are manually operated shut-off valves in a sturdy polymer design featuring integrated push-in connectors for quick tube installation . Designed for in-line installation, screw-in mounting, or bulkhead fitting configurations, these 2/2-way bistable ball valves provide reliable compressed air shut-off and are available in thread/push-in or push-in/push-in connection variants .
Key Features & Advantages:
Integrated Push-In Connectors: Features QS push-in connectors (4 mm, 6 mm, or 12 mm) for quick and secure tube installation, eliminating the need for separate fittings and reducing potential leak points .
2/2 Bistable Valve Function: Remains in its switched position (open or closed) without continuous energy input, providing stable shut-off for compressed air supply isolation .
Multiple Installation Options: Supports in-line installation, screw-in mounting via male thread, or bulkhead fitting configurations, offering flexibility for diverse mounting requirements .
Sturdy Polymer Design: PBT (Polybutylene Terephthalate) housing with robust construction provides durability and corrosion resistance for industrial pneumatic systems .
Wide Operating Pressure Range: Operates reliably from -1 bar vacuum to 10 bar positive pressure (depending on variant), suitable for both vacuum and compressed air applications .
