Airtac 3A200 Pneumatic Control Valve 3A21008NO
A cropped merino wool cardigan taken up a notch, thanks to the flecks of metallic thread throughout. We love it even more paired with the matching sweater-pants.
2. Double pneumatic pilot design with memory function;
3. Precision-machined internal bores with special surface treatment deliver low friction resistance, minimal actuation pressure, and extended service life;
4. Oil-free lubrication system requiring no maintenance;
5. Multi-position mounting capability for flexible installation and operation;
6. Compatible with base manifold valve blocks to optimize space utilization.
