A NAMUR-standard pneumatic actuator is a quarter-turn actuator whose accessory interface follows NAMUR Recommendation NE155, so pilot solenoid valves, position sensors and limit-switch boxes from different makers can be swapped without adapters. EU packaging machinery buyers should confirm NE155 interfaces, EN ISO 5211 valve mounting, torque margin, fail-safe position and compressed-air purity class before order release.
Direct Answer
Defines a NAMUR-standard pneumatic actuator as a quarter-turn actuator with an NE155 accessory interface and lists the five points EU buyers must confirm before order release.
Why Packaging OEMs Standardise on the NAMUR Interface
Explains that a shared NAMUR accessory footprint standardises valve islands, spare parts and drawings across filling, capping, labelling and cartoning lines, and that the interface does not fix torque or body material.

What EU Buyers Should Verify in Writing
Notes that Regulation (EU) 2023/1230 applies from 20 January 2027, that components still need consistent data for the technical file, and lists three written confirmations before order release.

Frequently Asked Questions
- FAQ Do NAMUR actuators fit any pneumatic valve?
No. NE155 covers the accessory interface between the actuator and its pilot valve or switch box. The actuator-to-valve connection is separate, usually governed by EN ISO 5211 flange size and valve stem dimensions. Both must match. - FAQ Can I use a NAMUR solenoid valve from another brand?
Yes — that is the purpose of the standard interface. Because the pilot valve port pattern is standardised, a NAMUR solenoid from another maker can normally be fitted without an adapter. Confirm voltage, function (3/2 or 5/2) and manual override before ordering. - FAQ What is the typical MOQ and lead time?
MOQ and lead time depend on model, size and configuration. Send the model code, quantity and required delivery window for a firm answer. - FAQ What information do you need to confirm the model?
Valve type and size, required torque, air supply pressure, single-acting or double-acting, fail-safe position, mounting standard, solenoid voltage and connection, and ambient temperature where the line runs hot or cold. - FAQ Can I get a drawing or photos before ordering?
Yes. Request a dimensioned drawing, torque table and photos of the configuration. Checking mounting dimensions against your valve drawing before order release avoids returns. - FAQ Do you supply samples?
Sample quantities are usually possible for standard configurations. Confirm samples together with MOQ and lead time, because customised units may not be available as samples.
