III. Key Parameters
1. Nominal Diameter DN12, opening pressure 0.45MPa (4.5bar), high-pressure version (low-pressure LV-12-25 in the same series is 0.25MPa)
2. Rated Pressure: 32MPa, Kawasaki original valve core, high-strength valve body
3. Installation Thread: Cartridge type, installed in the front total return oil passage of the hydraulic oil radiator
IV. Installation Location
In the main control valve return oil → radiator → hydraulic oil tank intermediate pipeline, at the radiator interface in the oil tank compartment, used in combination with LV-16-25A (60171840) for high and low pressure.
V. Function and Role
1. Allow forward flow of hydraulic oil, lock when stopped to prevent backflow of hydraulic oil from the oil tank into the radiator
2. Isolate the impact of self-returning oil during shutdown on the radiator core, control oil temperature, and prevent high-temperature arm drop
3. Valve Core Failure: Sudden oil temperature rise, boom natural drop, abnormal return oil noise, slow operation
