ROSS Controls D2773A8985 Solenoid Pilot Valve

ROSS Controls D2773A8985 is a solenoid-pilot valve from the 27 Series designed for industrial pneumatic systems, providing remote electrical control with a built‑in manual lockout energy isolation (L-O-X) and an air‑dump function. The unit is specified for 24 VDC operation and uses 1-1/2" NPT ports, making it suitable for standard‑temperature applications where robust isolation and controlled exhaust are required. As a poppet valve in the classic 27 Series, it accepts a solenoid pilot to shift the main flow path and enable or depressurize downstream equipment, while the L‑O‑X mechanism prevents unintended re‑energization during maintenance by locking the valve in the safe, depressurized state. Typical applications include isolating compressed air to machinery for service, remote actuation of pneumatic circuits, and safe exhaust of line pressure via the integrated air dump when the solenoid is de‑energized.
