ASCO 8317NSMP is a 3‑way, quick‑exhaust solenoid valve in ASCO’s Series 317 lineup, designed to vent a pneumatic line to 0 psi through an exhaust orifice for rapid actuation of downstream valves. The brass‑bodied valve uses 1/4" NPT ports and is commonly configured as a normally closed 3‑way device, with coil configurations including 120 VAC options suitable for air or inert gas service. In typical ASCO specifications, these valves are rated for operating pressures up to about 150 psi, enabling fast venting in automation, packaging, and process control applications. The NSMP designation identifies this kit/variant of the 8317 family as stocked by distributors for streamlined installation in compact pneumatic circuits.
