The valve consists of a valve body, a valve cover, a valve core and other components, among which the valve core is one of the core components of the valve. The valve core controls the flow between the inlet and outlet by moving up and down. Generally, there is a small hole on the valve core, which is called a regulating hole or a pressure-stabilizing hole. The small hole on the valve core is an important component in the valve, which can be used together with other components to control and adjust the valve.
