Festo ISO Cylinder DNC-40-430-PPV-A

Key Features & Advantages

• International standard compliance – Fully conforms to ISO 15552, ensuring interchangeability with other standard cylinders that share the same mounting interface.

• Double-acting operation – Compressed air drives the piston in both advance and return strokes, providing force in both directions for efficient bidirectional motion.

• Flexible cushioning system – Available with fixed cushioning or adjustable pneumatic cushioning at both ends (often indicated by “PPV” in the type code). Adjustable cushioning optimises deceleration based on load and speed, reducing impact.

• Convenient position sensing – Three sides of the cylinder barrel feature integrated sensor slots for mounting proximity sensors (e.g., electronic SM series or pneumatic SMPO series), enabling non-contact position detection. Sensors can be flush‑mounted and are easy to replace.

• Robust materials:

  • Barrel – Forged aluminium alloy with a smooth anodised surface for corrosion and wear resistance.

  • End caps – Die‑cast aluminium.

  • Piston rod – High‑alloy steel for durability.

  • Seals – TPE‑U(PU) material ensures reliable sealing performance.

• Space‑saving design – The compact construction saves approximately 11% installation space compared to conventional cylinders.

Main Technical Specifications

• Bore diameters – Standard sizes range from 32 mm to 125 mm.

• Stroke – Standard strokes from 25 mm to 500 mm; special strokes up to 2,000 mm available on request (minimum 10 mm).

• Operating pressure – 0.06 MPa to 1.2 MPa.

• Theoretical output force – Depending on bore size, approx. 415 N to 7,363 N.

• Ambient temperature – Standard versions: ‑20°C to +80°C; special versions (e.g., S6) up to 120°C.

Extensive Variants & Mounting Accessories

The DNC series is built on a modular system, offering over 20 variants and a comprehensive range of mounting accessories to suit diverse applications.

• Common variants – Include square piston rod (Q), extended piston rod (K8), internal/external thread on piston rod (K2/K3), heat‑resistant seals, and more.

• Valve variants – Some models allow direct integration of single or double solenoid valves on the cylinder, optionally mounted on the right or left side.

• Mounting options – A wide selection of mounting attachments enables installation in virtually any position.

Example Type Code Interpretation

Take the common model DNC‑63‑100‑PPV‑A as an example:

• DNC – Product series (standard cylinder).

• 63 – Bore diameter in mm.

• 100 – Stroke in mm.

• PPV – Adjustable pneumatic cushioning at both ends.

• A – May indicate a standard version or a specific piston‑rod design.
