ASCO 8290A384 Normally Closed Disc Angle Body Piston Valve

ASCO 8290A384 is a two‑way normally closed angle‑body piston valve with a bronze body and 1/2 in nominal pipe size, designed for compact direct control in fluid lines. This entry under the disc device features a 50 mm (2 in) valve head diameter, a Cv of about 5.7, and a flow path that enters under the disc for reliable shutoff. Sealing material is PTFE, and the valve accepts media temperatures up to 366°F (187°C). It is rated for up to 240 psi with water and up to 150 psi with steam, enabling service across water, air, and light fluids. The valve is offered with a 50 mm operator size for actuation and is intended to replace motorized or air‑actuated ball valve packages in tight installations, delivering a compact, normally closed solution with tight seating. Typical applications include process piping in water or air systems where precise, leak‑free shutoff is required and space is at a premium.
