Brass Body, Direct-Acting Valve

The ASCO 8030G083 is a direct-acting, normally open solenoid valve with a brass body and NPTF threads. It suits maintenance engineers and OEM integrators who need reliable on-off control of air, inert gases or water in low-pressure lines. The compact 2-way, 2-position design fits horizontal or vertical mounting without special brackets. Buyers who require higher pressure differentials or larger flow paths should look elsewhere.

Low-Pressure Range and Temperature Headroom

The valve operates from 0 to 2 psi differential for all compatible media, so it handles vacuum and very low-pressure systems comfortably. Ambient temperatures from 14°F to 140°F and fluid temperatures up to 180°F give wide environmental headroom. Beyond 2 psi the coil cannot overcome the pressure difference, so the valve will not close reliably.

120 V AC Coil and Class F Insulation

The included coil draws 10.1 W at 120 V AC and carries Class F insulation for thermal endurance. Power must be a stable 120 V AC supply; other voltages or DC sources are not supported by this coil. The 3/4 inch orifice and NPTF connections fix the mechanical interface, so pipework must match those dimensions exactly.

Questions about this item

Will the 3/4 in NPTF threads on this ASCO 8030G083 match the 3/4 in NPT fittings already on my older piping?

Yes, the valve uses 3/4 in NPTF inlet and outlet threads which are compatible with standard 3/4 in NPT pipe fittings commonly found on existing installations.

How can I confirm the 120V AC coil is energising correctly after I wire it up?

Apply 120V AC power and listen for the solenoid click; the valve should shift from its normally open position to closed, and you can verify flow stops by checking downstream pressure or sight glass.

Does the box include the coil and any gaskets, or do I need to order a 10.1 W replacement coil separately?

The coil rated 10.1 W at 120V AC is supplied with the valve; no separate coil purchase is required, and the brass body uses its own NPTF thread seal so extra gaskets are not included.
