NAD is a compact diaphragm valve opened and closed by pilot air. NC, NO and double acting types are available, in a general purpose version for air, inert gas, water and non-corrosive liquids and a NADV version for low vacuum (air, water). The port is Rc3/8, the body is stainless steel casting and the seal is ethylene propylene rubber.
