ELIPTIX R-20 SM, is a Weir-type, Elliptical-shaped Diaphragm, 3-way, Pressure Sustaining Control Valve, with manual override, activated by line pressure. The valve maintains a steady, preset pressure in the network, upstream of its location. Should upstream pressure exceed preset values, the valve opens to increase network flow, reducing upstream pressure. Should upstream pressure fall below preset values, the valve closes drip-tight. The manual override selector valve allows opening or closing the main valve to be performed manually.
