Mixing Valves 720 - 724 Brass
Control Description The 4-Way Brass Mixing Valves 720, 721, 722, 723, and 724 are used to mix supply water from a heat source with water returning from a system. They are designed for use in either closed loop or open loop hydronic systems. All valves have standard female NPT threads. The valve provides a maximum leak through rate of 1% to allow for water expansion during temperature changes. The valve position can be manually set using the handle. An Actuating Motor 741 can be used to automatically operate the valve.
