The EB-45 Series is a lead-free1 half-cartridge based pressure reducing and regulating valve with a bronze body. The valve construction is similar to a traditional regulator in that it retains a separate spring chamber and adjusting screw, but offers the simplicity and maintenance benefits of a cartridge based valve. The EB-45 is assembled using modular construction methods and features end connections threaded for both FIP and union in 1/2 in through 2 in sizes. A connection for a pressure gauge is also available for 3/4 in and 1 in models. The EB-45 is intended for use where supply line pressure does not exceed 300 psi (400 psi 1/2 in, 3/4 in and 1 in). The EB-45 pressure regulators are supplied by the factory with a standard delivery setting of 45 psi. The outlet pressure can be adjusted from 10 to 70 psi without changing the spring. This regulator is suited for either cold or hot (to 180 deg F) water service.
