A NAMUR \u96fb\u78c1\u95a5<\/strong> \u2014 the pilot that turns an electrical signal into actuator movement. It bolts straight onto the NAMUR interface on top of a pneumatic actuator, with no fittings and no tubing between the two.<\/p>\n

Two versions, and which one you need depends on your actuator<\/strong>. Get this wrong and the valve will not work. The table below tells you which one to order.<\/p>\n

5\/2 or 3\/2? Match It to Your Actuator<\/h2>\n

This is the single most common ordering mistake in pneumatic valve packages. If you are not sure which actuator you have, tell us the model and we will tell you which solenoid it takes.<\/p>\n

Will It Fit My Actuator?<\/h2>\n

If your actuator has a NAMUR \u4ecb\u9762<\/strong> on top \u2014 the standard bolt pattern and the two air ports machined into the actuator body \u2014 this solenoid bolts straight on. No adapter, no piping.<\/p>\n

And if you are buying the actuator from us as well: every pneumatic actuator we make has a NAMUR interface.<\/strong> The solenoid, the actuator and the valve all come from us, assembled and tested together, so there is nothing to match up on site.<\/p>\n
