ASCO 8290A21 Valve

The ASCO 8290A21 Valve is a high-performance 2-way normally closed angle body piston valve designed for demanding industrial applications. Featuring a 1 1/2 inch NPT connection and a robust angled bronze body, this air-operated valve utilizes a 90mm entry under disc pilot operator to prevent water hammer and ensure smooth actuation. With an impressive 52 Cv flow coefficient, it manages high-volume flow for air, water, fluids, and steam. The durable Teflon (PTFE) seat provides exceptional thermal resistance, allowing for reliable operation across a wide temperature range. Engineered for versatility, it handles pressure ratings from 60-150 PSI for pilot air or water and up to 120 PSI for process media. This heavy-duty pneumatic valve is ideal for rapid cycling in food and beverage, textile, and chemical processing environments where reliability is paramount.
