ASCO 8308A40 Solenoid Valve is a direct-acting, 3‑way valve in the ASCO 8308 family with a tamper‑proof manual‑reset design and an optional release latch for controlled re‑setting in safety‑critical systems. It uses 1/4" NPT ports (1/4" pipe size) and is intended for air, inert gas, water, and light oil service, making it suitable for process‑control applications where fail‑safe operation matters. The valve operates on 120 VAC at 60 Hz (some variants list 110–120 VAC, 50/60 Hz) and is designed for reliable actuation while preventing inadvertent starts due to the manual reset feature. The release‑latch variant supports secure retraction and re‑arm after actuation, enabling deterministic maintenance in critical environments.
