The Nakakita NST-732 is a self-actuated, 3-way temperature control valve designed for high-reliability applications in marine and industrial environments. It operates without any external power source, such as electricity or compressed air, by utilizing the principle of liquid expansion within its thermal sensing unit. This robust valve is engineered to automatically regulate the temperature of fluids like cooling water, lubricating oil, and fuel oil by mixing or diverting the flow. Its simple construction ensures dependable performance, easy installation, and minimal maintenance, making it an ideal solution for temperature control in diesel engines, turbines, compressors, and heat exchangers.
