The EB45 Series is a lead-free half cartridge based =pressure reducing and regulating valve with a bronze body. Its design offers the performance of a high end, cartridge-based valve and the price of a traditional regulator. 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 EB45 pressure regulator valve comes factory set at 45 psi but may be adjusted between 10-70 psi. It can be used for both commercial and domestic water applications.
