Making a Decision on Selecting Your Pneumatic Component Systems

Introduction

Whether you’re building or upgrading an automated system, choosing the right pneumatic components is one of the most important decisions you’ll make. By now, you already understand how to avoid a supply chain crisis, planning, selecting dependable vendors, and standardizing where possible. The next step is making sure the components themselves meet the performance, durability, and compatibility requirements of your machine.

Below are the key considerations you should keep in mind when evaluating pneumatic component systems, as well as why standardized ISO cylinder families and modular valve terminal platforms like Festo’s offer strong long‑term advantages.

Products

DSNU — Round Body Cylinders (ISO 6432)

When your envelope is tight and cycle counts are high, you need a round-body cylinder built for the long run, not just one that fits the specs. DSNU is the compact automation workhorse that proves small doesn't mean compromised. Whether you're indexing, clamping, or actuating in a crowded cell, it delivers where proprietary alternatives fall short.

  • Bore sizes from 8mm to 25mm per ISO 6432

  • Dimensional interchangeability without sacrificing performance

  • Superior cushioning quality and seal longevity under high-cycle conditions

  • Clean, reliable sensor integration

DSBC/DSBG — Profile Cylinder (ISO 15552)

Ideal for applications where force and stroke length drive the design, clamping, pressing, lifting, and transfer. When you step up from compact to profile, you need more than a bigger bore. You need a cylinder that's been engineered for the demands that come with it like higher loads, longer strokes, and the accessories to mount to your new machine.

  • Bore sizes from 32mm to 320mm under ISO 15552

  • Magnetic piston standard for straightforward proximity switch integration

  • Bidirectional adjustable cushioning across the entire bore range

  • Accessory ecosystem: rod attachments, cylinder mounts, integrated guides

  • Precision bearing and seal design sustain stroke accuracy and side-load performance over time

ADN — Compact Cylinder (ISO 21287)

Built for short stroke, high actuation in tight machine envelopes. The ADN's block design solves a problem that comes up constantly in modern machine design: You need real actuation force, but you have very little room to work with. Instead of compromising on one or the other, the ADN is engineered to deliver both without digging into your budget.

  • Bore sizes from 20mm to 100mm

  • Flat block profile installs cleanly in multi-axis cells

  • Adjustable pneumatic cushioning with standard magnetic piston for position detection

  • Repeatable end-position accuracy and long service life in high-cycle, precision-critical applications

VTSA — Valve Manifold (ISO 5599)

Operators who need scalable, fieldbus‑integrated pneumatic control often start with individually mounted valves, but as machines become more complex and networks improve, that scattered setup leads to extra hardware, more failure points, tougher troubleshooting, and less flexibility when designs change. The VTSA avoids these problems by giving you a cleaner, centralized architecture.

  • Single manifold body supports multiple valve series

  • Compatible with CC-Link IE Field Basic, Ethernet/IP, PROFINET, EtherCAT networks

  • Built-in pressure zone separation supports plant floor safety requirements

  • Cleaner, more cost-efficient path forward for modern network infrastructure
