CKD GNAB/GNABV Air Operated 2-Port Manifold Valve (Compact Cylinder Valve)

GNAB is the manifold version of the NAB compact cylinder valve, with the valves mounted on a sub-plate. It is configured with 2 to 10 stations, and the air supply method can be common supply or individual supply. A general purpose version for air, water and gas and a GNABV version for low vacuum (air, water) are available, with Rc1/4 and Rc3/8 ports.
