What is the coolant bypass valve and its function?

The valve installed on the bypass pipeline is called a bypass valve. Bypass valve is also called self-operated bypass differential pressure valve. Self-operated self-operated differential pressure control valve Each lubricating oil filtration system (oil) and hydraulic oil filtration system is equipped with a bypass valve, which is used to ensure that the main components of the system can be lubricated by oil when the oil temperature is low or the filter is blocked by too many impurities. The bypass valve can be installed on the filter or on the filter base. The setting of bypass valve varies according to the technical specifications of OEM. If the bypass valve is not mentioned, it means that the bypass valve is not installed in the filter, but it must have been installed in the lubricating oil circuit of the host system. Note: When replacing the filter, do not replace the filter with a bypass valve with a filter without a bypass valve. Bypass valve is also called self-operated bypass differential pressure valve. Self-operated differential pressure control valve The self-operated differential pressure control valve (bypass-C) has an automatic valve plug in the closed state within the control range. When the pressure difference between the two ends of the valve exceeds the preset value, the valve plug automatically opens. Under the action of pressure-sensitive film, the opening is automatically adjusted to keep the pressure difference between the two ends of the valve relatively constant. The valve works by its own pressure difference, without any external power, and its performance is reliable.
