Oil Temperature Valve (HOTV)
The Hansen Oil Temperature Valve is a 3-way mixing valve used to accurately control the oil temperature of screw compressors or other oil-cooling circuits within appropriate design parameters. The internal thermostatic element modulates to maintain a near constant temperature at the outlet of the valve.
As oil and refrigerant are circulated through the screw compressor, the oil is heated. The hot oil is fed to the valve and it is also fed to a heat exchanger, which provides cold oil to the opposite side of the valve. The thermostatic element modulates the flow of oil from the cold oil port and the hot oil port to maintain the nominal temperature setting at the outlet.
