Balem 132-040 Pressure Reducing/Sustaining & Check Valve

Model 132-040 combined Pressure Reducing(Model 562) and Pressure Sustaining(Model 573) and Check valve maintains inlet pressure change and/or downstream pressure flow rate to a predetermined minimum pressure. Also prevents functions if inlet pressure drops lower than preset pressure and once downstream pressure is higher than inlet pressure, the valve closes to prevent backflow caused by back pressure.
