Recently completed 2 Senior Housing projects, with each project requiring 90 radiation valves. Due to the tight budget invloved , we searched for an inexpensive valve comparable to the model we typically use. We tried the KZ series valves and the fitter liked the idea that they were sweat valves and cut his installation time down significantly. We were able to save roughly $25 per each valve/acuator assembly and have had no problems to date.
Sincerely,
Dave
