Product Description
The Festo HW-6-38 is a manually operated selector switch (directional control valve) featuring a flat sliding mechanism that connects the supply port to one of six outputs, with non-switched outputs sharing a common exhaust channel . Designed for direct actuation with a rotary handle and position indicator arrow, this 8/6 bistable valve operates without overlap and includes ball detents for each of the six switch positions .
Key Features & Advantages
-
8/6 Bistable Valve Function: Supplies compressed air from port 1 to one of six output ports, allowing selection of six different pneumatic circuits from a single supply source .
-
180 L/min Flow Rate with M5 Ports: Delivers 180 L/min standard nominal flow through M5 threaded connections, suitable for controlling small pneumatic actuators and pilot systems .
-
Six Positions with Ball Detent Locking: Each of the six switching positions is secured by a ball detent mechanism, providing clear tactile feedback and stable position holding .
-
Non-Overlapping Switching Design: Reverse switching is achieved without overlap (non-overlapping function), preventing cross-flow between ports during position changes .
-
Direct Actuation with Visual Position Indicator: Features a rotary handle with an arrow that indicates the current switching position, plus optional adhesive ring scale (HWF-6-38) for position labeling .
