Frequently asked questions — Pneumatic Accessories

• How to choose between pneumatic accessories and specialised pneumatic components?

  The choice depends on the structure of your circuit. Pneumatic accessories, including solutions from ALGI, LEGRIS, TRICOFLEX and HD AIR, make it possible to design overall architectures by integrating connectors and valves. If your need specifically concerns compressed air management or a precise actuator function, it is appropriate to turn to the dedicated sub-families. Analysing pressure, temperature and material compatibility constraints remains the decisive factor in selecting the component best suited to your industrial application.
• What are the regulatory requirements for designing a pneumatic circuit?

  Compliance with ISO standards is essential for the safety and performance of systems. ISO 4414 governs all safety rules for pneumatic fluid power systems. For control systems, valve design may be aligned with ISO 5599. With regard to actuators, it is necessary to comply with dimensional standards such as ISO 15552 for tie-rod cylinders from 32 to 320 mm or ISO 6432 for mini-cylinders with bore sizes between 8 and 25 mm.
• How to avoid pressure drops in pneumatic networks?

  Preventing pressure drops relies primarily on paying particular attention to pneumatic connectors. It is essential to size components according to the flow rates required by your application and to verify the compatibility of materials with the working environment. Careful installation, in line with the technical recommendations of manufacturers such as LEGRIS or TRICOFLEX, ensures the longevity of the network. Mastering these parameters, combined with compliance with applicable standards, guarantees optimal and safe operation of compressed air circuits.
• Why is valve sizing critical for actuators?

  Valve sizing must precisely meet the cycle and speed requirements of the actuators to ensure the expected operation. Incorrect sizing may impair system responsiveness or lead to malfunctions. For a consistent design, it is recommended to refer to ISO 5599, which governs the use of valves in control systems. The entire selection, including valves and connectors, must be harmonised to meet the specific technical requirements of each industrial application.
