Control Description The Mixing Expansion Module 441 is designed to operate any of the tekmar 3-way and 4-way brass mixing valves from type 710 through type 724. The 441 provides 6 N=m (53 in=lbs) of torque over a 90¼ rotation. The 441 is controlled through digital communication on tekmarNet+4 systems. The 441 requires the use of a tN4 System Control that includes a mix temperature bus.
