II. Instruction
The OTRV is a three-way valve for refrigeration. It is used to maintain the oil temperature of the compressor at a stable level by mixing the hot oil and cold oil in the lubricating oil system of the screw compressor or centrifugal compressor. It can also be used Used as a directional control valve.
The valve body interface is marked with A\B\C. When used as an oil temperature regulating valve, A is connected to the compressor, B is connected to the high-temperature oil, and C is connected to the cold oil. When the temperature reaches the temperature of the sensing element, the flow of B and C is automatically controlled. So as to achieve the purpose of adjusting the oil temperature. When used as a directional reversing valve, A is the inlet, B is connected to the compressor pipeline, and C is connected to the cooling oil.
