ROSS 2768C5901 Three Quarter Inch Check Valve

ROSS 2768C5901 is a 3/4" inline pilot-operated check valve with exhaust, part of ROSS Controls' 27 Series PO Check Valves. The model uses BSPP threads for body and port connections (prefix D), with a 3/4" body size and a pilot port configured at 1/8-27 NPT. This valve provides a two-port flow path with an exhaust function, enabling backflow prevention while allowing the controlled side to vent when the pilot is engaged. It is designed for load-holding and backflow protection in pneumatic circuits, making it suitable for holding cylinders in automation cells, clamps, and safety-related actuation where maintaining position after power loss is essential. Inline-mounted for easy installation, the 2768C5901 supports typical 3/4" pneumatic plumbing and uses standard BSPP thread variants where specified. As a member of the 27 Series, it shares the family’s emphasis on reliable control of pneumatic actuation, with exhaust relief included to manage pressure on the load side during pilot activation. This model number indicates a 3/4" PO check with exhaust, suitable for compact safety and clamping applications in industrial automation.
