Airtac NRV Non-Return Valve NRV08
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.
