Resideo Differential Pressure Regulator, Angle, D146M Series, 1-1/4 in Nominal Size, FNPT, 85 psi, 230 deg F Operating, 50 gpm, Brass Body, EPDM Diaphragm, 8-1/2 in H x 4-1/4 in W, Import
The differential pressure regulator eliminates excessive pump head pressure, when most radiator valves are closed due to reduced demand, by controlling flow through a bypass line when the difference between supply/return exceeds the setpoint.
