Thermostatic Control Valves - Model B Overview AMOT model B thermostatic valves are available in a wide selection of sizes and settings to fill a multitude of fluid temperature control requirements. These valves may be mounted in any position and use the proven expanding wax principle to actuate the 3-way temperature element assemblies. The model B valves may be used for diverting or mixing service. They make very economical temperature limiting valves for engine and lubricating oil cooling, and to prevent scalding in home, motel or hotel hot water supply systems. Radiant heating systems can...

Thermostatic Control Valves - Model B Applications Diverting Applications Mixing Applications 2-way Water Saving Applications When valves are used for diverting service, the inlet is Port A (temperature sensing port), with Port C being connected to the cooler, and Port B connected to the cooler by-pass line. When valves are used for mixing service, Port C is the cold fluid inlet port from the cooler, Port B is the hot by-pass fluid inlet, and Port A the common outlet. Port A is the temperature sensing port and will mix the hot and cold fluids in the correct proportion so as to produce the desired...

It is defined as the flow rate in cubic meters per hour (m 3/h) of water at a temperature of 16º celsius with a pressure drop across the valve of 1 bar. Cv is the imperial coefficient. It is defined as the flow rate in US Gallons per minute [gpm] of water at a temperature of 60º fahrenheit with a pressure drop across the valve...
