The Asco 8290A385 Solenoid Valve is a pressure-operated, direct-acting angle-body piston valve with a normally closed configuration and flow entry under the disc. It features a robust bronze body and a high Cv rating of 11, and can handle both fluids and steam up to 150 psi. This valve is well-suited for steam header branches, hot water rinse manifolds, and CIP utility drops requiring durable performance and compact installation.
