CircuitSolver® is a thermostatic balancing valve that automatically and continuously adjusts flow to maintain the desired temperature in a domestic hot water supply line. Since the CircuitSolver® responds to water temperature to control the flow entering the recirculation line it eliminates the need to manually balance the system. The “CSUASTD-D” version CircuitSolver® incorporates a second actuator to reopen the valve during a thermal disinfection process, an optional check valve, isolated ball valves, and a strainer. The featured strainer (20 mesh) must be maintained in order to avoid flow obstruction.
