Overview
The Festo DNG-50-25PPV-A is an ISO 15552 standard double-acting pneumatic cylinder engineered for precision linear motion in automation systems. With a 50mm bore diameter and 25mm stroke length, this unit operates across a pressure range of 0.5 to 12 bar, making it suitable for light to medium-duty industrial applications. The PPV designation indicates pneumatic cushioning, adjustable on both ends, which protects the cylinder and load from shock and impact during end-of-stroke movement.
Key Features
- Double-acting design with pilot-operated poppet valves (PPV) for smooth cushioning
