The Asco 8263G308 Solenoid Valve is a direct-acting, normally closed 2-way valve designed for low-pressure steam service in high-temperature environments. Its internal components are engineered to resist heat-induced wear and maintain a tight seal over repeated cycles. The valve’s fast-acting performance makes it suitable for discharge and vapor control in compact heating systems.
