NAB is a compact cylinder valve opened and closed by pilot air. NC, NO and double acting types are available, in a general purpose version for air, water and gas and a NABV version for low vacuum (air, water). Ports are Rc1/4 and Rc3/8. The body is selected from copper alloy or stainless steel, and the seal from nitrile rubber (NBR) or fluoro rubber (FKM).
