The Cash Acme SharkBite EB-45DSB is a half-cartridge-based pressure reducing and regulating valve with a bronze body. The valve resembles the traditional regulators with a spring chamber and an adjusting screw but offers the performance of a cartridge-based valve. The SharkBite EB-45DSB is assembled using modular construction methods and features SharkBite connections in 1/2 in. through 1 in. sizes. Connect the SharkBite pressure reducing and regulating valve to copper tubing, and CTS CPVC and PEX in seconds with ease. These valves are supplied by the factory with a standard delivery setting of 45 psi. The outlet pressure can be adjusted from 10-70 psi without changing the spring. The EB-45 is intended for use where supply line pressure does not exceed 200 psi. This regulator is suited for either cold or hot (to 180F) water service.
