Operation: Flomatic 816 Ward stainless steel check valves are engineered to provide reliable, maintenance-free performance when properly sized and installed in accordance with system flow and pressure requirements. The internal spring-loaded plunger minimizes backflow and reduces hydraulic shock in pressurized systems.

Construction: The Flomatic 816 valve body and all internal components are constructed from 316 stainless steel to withstand demanding system pressures, corrosive environments, and elevated temperatures. The PTFE soft seat provides tight shutoff, while the Y-pattern body enhances flow characteristics and permits vertical or horizontal installation per manufacturer guidance.

Proud to manufacture high-quality valves built to last since 1933, Flomatic® Valves is an American valve manufacturer certified under ISO 9001 and ISO 14001 quality and environmental management systems.
