Airtac NRV Non-Return Valve NRV10
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.

The NRV10 features a low cracking pressure design with precision-machined aluminum body for bidirectional flow blocking. Its asymmetric spring chamber design prevents particulate accumulation, making it ideal for contaminated air environments. The valve maintains consistent performance through 1 million cycles minimum.
- Air compressor return line protection
- Vacuum pump system backflow prevention
- Pneumatic cylinder exhaust port locking
- Medical gas distribution systems
- Hydraulic accumulator isolation (oil-resistant seals required)
- CNC machine tool air circuit safety
Installation guidelines:
Arrow direction must align with primary flow path. For vertical installation,
orient spring chamber downward. Use PTFE tape on male threads only,
avoiding entry into flow channels. Pre-flush pipelines before commissioning.
