Purpose:

LZF Temperature Auto Regulating Valve is called Automatic Temperature Controller, is mainly suitable for automatic temperature adjusting of fresh water system and lub oil system of marine machinery installations and also suitable for automatic temperature adjusting of cooling system & lubricating system for diesel engine, steam turbine, gas turbine and gears used onshore, promoting heat energy coefficient of utilization and economic benefits of machinery installations.

Working Principle:

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.
