| THE STEAM FITTINGS CO. Ltd., West Drayton, Mdx. THE "SAMSON" Safety Mixing Valve For HOT AND COLD WATER or STEAM AND WATER, With AUTOMATIC TEMPERATURE REGULATION. PATENTED. Diagram 'TYPE A' labels: R, THERMOMETER POCKET, H, A, MIXED LIQUID, HOT, COLD, B, 100 TYPE "A.{Mr Adams}" For Hot and Cold Water only. Diagram 'TYPE B' labels: R, R, MIXTURE, H, B, HOT, COLD, 99 TYPE "B." For Hot and Cold Water or Steam and Water. THE "SAMSON" SAFETY MIXING VALVE automatically keeps the water at the outlet at a constant temperature independent of variations of the temperature at the inlets. The regulation is effected in the following way. The mixed water flows through a cylinder fitted with a very sensitive temperature regulator, which actuates the hot and cold water valve if any variation of the temperature of the mixture occurs. In the larger sizes two separate valves are provided, controlled by two thermostats. The “Samson” Mixing Valve is of the greatest utility in Public Baths, Hotels, Hospitals, where it can also be applied to “continuous baths” for distribution of warm water in installations where a large quantity is required at certain hours, when calorifiers generally fail to meet the demand satisfactorily. In such cases the water in the calorifier can be kept, by means of our “Samson” Regulator, at or near boiling point, and a mixing valve regulates the distribution temperature. They are also well adapted for maintaining constant temperature in hot water heating systems with accelerated circulation. The temperature of the mixed water can be varied between 75º – 200º Fahr. L.
