Noise can be present in a multiple actuator manifold if only one or two actuators are open. The pump is sized for the total flow rate and highest pressure drop of all the circuits. With just one or two circuits calling for heat, the pump is oversized, possibly causing noise. The pressure differential by-pass valve eliminates water velocity noise and water hammer. With this valve, high-pressure pumps cannot exceed actuator close-off pressure. Pump life increases because of minimal pressure surging as actuators open and close. There is always correct and constant flow regardless of the number of actuators open. The valve adjusts from 2.18 to 11.6 psi using a graduated knob. Water bypass capacity is 0.6 to 9 gpm. Maximum pressure is 145 psi, maximum temperature is 230 deg F. The knob is set and locked with a set screw to prevent tampering.
