Airtac NRV Non-Return Valve NRV15
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、Prevents backflow phenomena caused by pressure decay in air supply systems or excessive consumption-induced pressure drops;
3、Features a large effective flow area for optimized pneumatic performance;
4、Incorporates injection-molded POM valve core and elastomer-sealed orifice, engineered with compact construction for reliability.

High-flow non-return valve with low cracking pressure, featuring a precision ground stainless steel ball and corrosion-resistant construction. The integrated spring mechanism ensures immediate shutoff during pressure reversal. Compatible with air, inert gases, and non-lubricated media. Includes anti-vibration pads for stable mounting.
- Pneumatic cylinder backflow prevention
- Compressed air receiver safety loops
- Vacuum pump isolation systems
- Hydraulic accumulator circuits
- CNC machine tool lubrication units
Installation guidelines:
Arrow marking must align with primary flow direction. For horizontal mounting,
position spring chamber downward. Use thread sealant (PTFE tape recommended)
on male threads only. Perform monthly seal integrity checks in high-cycle applications.
