ASCO L8210G003MO Pilot Operated Solenoid Valve

ASCO RedHat 8210G003MO is a two‑way, pilot‑operated general‑service solenoid valve designed for high‑flow control of compressed air, inert gas, water, and light oils. It features a brass body with 3/4 in NPT connections and a normally closed starting configuration, delivering a Cv of 6.5 for strong flow with moderate pressure drop. As a pilot‑operated valve, it uses process pressure to shift the main path, enabling reliable actuation in compact form factors. The valve supports a maximum differential pressure of up to 250 psi for air/inert gas and operates over ambient temperatures of 32–125 °F (0–52 °C) with fluids rated from 32–180 °F (0–82 °C). Seals are typically NBR, and the brass‑body variant is common to this model line (with stainless options available in related 8210 variants). Coils for this family come in multiple voltages, including 120 VAC (60 Hz) and 24 VAC (or 24 VDC in some configurations), with coil power commonly specified around 6.1 W at 60 Hz for standard 120 VAC coils. This valve suits general automation tasks in pneumatic systems, water handling, car wash and laundry equipment, and other industrial applications where a robust, pilot‑operated valve provides dependable control and high flow.
