Marine Temperature Auto-Regulating Valve LZFT-80

LZFT is nodular iron Temperature Auto Regulating Valve, also called as Automatic Temperature Controller, is mainly suitable for automatic temperature adjusting of fresh water system and lub oil in cooling system of power units in marine & other kinds of ships. Our products have the features of working without any external power, pronging machine life and increasing economic benefit.

The temperature valve consists of a temperature sensor, a rotating valve, a mandril and a lever. According to the change of media's temperature, the temperature sensor controls the mandril to extend and shorten, causing the lever to drive and the valve to rotate. Together with the rotating valve, the flux that flow to the cooler and pass-by is regulated to adjust media's temperature.

When the mediua's temperature rises and reaches the lower limit of attemperator, the temperature sensor drives the lever and rotates the valve anticlockwise. So the pass-by pipe is closed and the cooler pipe is opened a little by little. When the media's temperature reaches the upper limit of sendsor, the pass-by pipe is closed and the cooler is opened completely. It is opposite direction between rising and falling process of temperature. The action of valve's working makes the media which temperature could be adjusted in range.
