Durable Construction: Heavy-duty bronze body and stainless steel strainers resist corrosion and scaling in harsh hydronic environments

Utility Thermostat

the KMC Controls VCZ series maintains linear flow characteristics for stable environmental control

Standard practice involves installing the valve at the highest point of the piping or tank where vacuum pockets are most likely to form

upright mounting is preferred to prevent oil accumulation
