Product Overview
The ROSS D2781A8900 / 266A86 is a heavy-duty pneumatic directional control valve engineered by ROSS Controls, a globally recognized authority in pneumatic and hydraulic safety valve technology. This double-valve assembly operates on a poppet-type, spool-actuated design that delivers positive sealing and high flow capacity for demanding industrial circuits. The D2781A8900 valve body is paired with the 266A86 base or manifold configuration, providing a complete, ready-to-install directional control solution. As a pneumatic directional control valve, it manages the start, stop, and direction of compressed air flow to cylinders, actuators, and other downstream pneumatic devices. Its robust construction and positive-seal poppet mechanism make it a preferred choice for applications requiring reliable, leak-free operation and rapid response in automated industrial systems.
