ROSS Controls D2768D4901 Pilot Operated Check Valve

ROSS Controls D2768D4901 is a 27 Series Pilot Operated Check Valve (PO Check Valve) configured as a 2‑way, 2‑position, pressure‑controlled device, designed for remote pilot actuation in pneumatic circuits. The 1/2 in body size uses an 1/8‑27 NPT pilot signal port (signal port code C1 for this size) to control the internal poppet, providing a Cv of 3.2 and a compact, high‑flow path suitable for load‑holding or backflow prevention in compact manifolds. Weighing about 3.5 lb and featuring standard NPT port threads, this valve integrates with common pneumatic plumbing and a pilot line to achieve precise, remote control of the main valve function.
