This 1/2 inch bronze combination fill valve and backflow preventer is for use in commercial and residential hydronic heating systems to provide make-up water to the boiler, and prevent backflow when supply pressure falls below system pressure. It consists of a bronze backflow preventer, model 9D and a bronze feed water pressure regulator, model 1156F, in one pre-assembled unit. The high capacity fill valve provides quick system filling and purging. It is designed for use in the boiler feed lines of hydronic heating systems and has 1/2 inch union solder inlet x NPT threaded outlet connections. The maximum pressure is 100 psi (6.9 bar).

Designed for maximum control functions and lock-up type applications. The double diaphragm, balanced valve design makes it possible to maintain steady outlet pressure control with widely varying inlet pressures.

A pound to inches regulator designed for use on residential, commercial and industrial applications where adequate inlet pressures are available.

Designed primarily for main burner and pilot load applications where precise control of tiny flows is an essential operating requirement.

Appliance regulators are typically the last regulator in the line and are mainly found within the appliances or equipment made by the manufacturer. They are designed for main burner and/or pilot applications where precise control of tiny to large flows is an essential operating requirement.

Intended for use with both main burner and pilot load applications. The double diaphragm, balanced valve design makes it possible to maintain steady outlet pressure control with widely varying inlet pressures.
