Thermostatic Control Valves

Thermostatic Temperature Control Valves provide reliable, automatic and accurate temperature control of fluids. These self-contained, 3-way temperature regulating valves may be used in either mixing or diverting applications and require no external power source. AMOT thermostatic valves provide years of trouble-free service and require minimal maintenance.
