This 3/8 in super sensitive lead free water pressure regulator is designed to meet low water pressure precision requirements. It is used in applications requiring low pressure, super sensitive regulation in systems using water or No. 2 fuel oil. The high ratio of the diaphragm to the orifice provides excellent performance and stability at a low reduced pressure. It is ideally suited for water requirements up to 2.5 gpm (9.5 lpm) and is suitable for the water pressure supply to the wall attachment of fluidic devices. It consists of a lead free brass body with a tee handle, FNPT connections, replaceable stainless steel seat, large diaphragm and 30 mesh stainless steel strainer. The reduced water pressure range is 0 to 20 psi with the water pressure set at 10 psi . The temperature range is 0 to 120 deg F .
