The CircuitSolver® Union Assembly (CSUA) is a thermostatic balancing valve with integrated M/F isolation valves and a union, designed for simplified installation and reduced leak points in domestic hot water recirculation systems. It is available in 1/2", 3/4", and 1" NPT sizes, with overall dimensions of 1.8 to 2.5 inches in diameter and 7.7 to 10.5 inches in length, depending on size. The valve operates at a maximum pressure of 200 psig (14 bar) and a maximum temperature of 250°F (121°C). It is self-actuating, automatically maintaining balance without manual adjustment, and meets NSF/ANSI/CAN 61 or 372 certification. The assembly arrives fully tested and includes lead-free brass components.
CircuitSolver® Union Assembly (CSUA)
We have gone one step further by adding isolation valves to either side of the CSU, making it the easiest and most efficient balancing valve to specify and install. Since it balances your system on its own, there are no additional labor costs. It arrives fully assembled and leak tested with all the components commonly specified with balancing valves. The M/F isolation valves mean fewer potential leak points and a compact profile. An integrated strainer is also available for water systems with particulate/dirt problems (Model CSUAS).
CircuitSolver® is a self-actuating thermostatic balancing valve that automatically and continuously maintains a set water temperature at the end of each domestic hot water supply. It solves the problem of delayed hot water delivery while completely eliminating the need for time consuming, expensive manual balancing procedures and equipment. By allowing only fluid that cools below the set point to flow to the return, CircuitSolver®also eliminates the need for oversized recirculation pumps which lead to pipeline erosion and energy waste.
