The Singer 106/206 PGM-2PR-630-SM Pressure Management Valve with Integral Backup hydraulically manages pressure around the clock to reduce water loss, save money and prevent unwanted pressure spikes that contribute to premature pipe failure. Built on the Singer 106-PGM or 206-PGM main valve, a simple field retrofit is possible using the paddle style orifice plate. The valve switches between high- and low-pressure pilots based on flow rate. The pressure-reducing pilots independently adjust to suit the optimal downstream pressure. Available in sizes 4”-12” (DN100-DN300) with a minimum pressure at the valve inlet of 29 PSI (200 kPa/2 barg).
