Product Description
The Festo J, JD, and VL series are pneumatically actuated directional control valves conforming to ISO 5599-1, featuring robust die-cast aluminum housings and piston spool design with soft sealing . These valves offer flow rates from 1,200 to 6,000 L/min and are ideal for applications requiring pneumatic pilot actuation, including ATEX-rated explosive environments .
Key Features & Advantages:
ISO 5599-1 Compliance: Manufactured to international ISO standards, ensuring seamless interchangeability with standard sub-bases and manifolds across ISO sizes 1 to 4 .
Pneumatic Actuation: Eliminates electrical components at the valve body, making these series ideal for hazardous locations (ATEX Zone 2/22) and environments where spark-free operation is required .
High Flow Capacity: Delivers exceptional flow rates from 1,200 L/min (J/JD ISO size 1) up to 6,000 L/min (VL ISO size 4), suitable for high-cycle and demanding pneumatic systems .
Flexible Valve Functions: Available in multiple configurations including 5/2-way (bistable), 5/2-way (bistable dominant for JD), and 5/3-way (center vented/exhausted for VL) .
Wide Operating Pressure Range: Operates reliably from -0.9 bar to 16 bar, supporting vacuum operation and positive pressure control in a single valve platform .
Reversible Flow Design: All series support reversible flow direction, providing installation flexibility and simplified system design .
