Product Description
WTFK Temperature Regulating Valve Unit
Product Introduction:
The Marine Temperature Regulating Valve Unit is a self-operated, mechanical temperature control system designed for marine engine rooms and auxiliary systems. It integrates a temperature sensor (thermal bulb), a capillary tube, and a control valve into a single unit. Without requiring any external power or compressed air, it automatically maintains fluid temperature at a preset value by mixing hot and cold media or regulating heating/cooling flow. This unit is ideal for harsh marine environments where reliability and simplicity are paramount.
WTFK temperature regulating valve unit consists of temperature regulator, regulating valve, filter, emergency shut-off valve, bypass valve, flange and other components. It is applicable to the heat exchanger, pre-heating fuel and central heating to control temperature in ship-manufacturing, chemical and other industries.
