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).\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"product__additional-details\"\u003e\n\u003cp
