Characteristics of Fluorine lined Check Valve

check valve In actual operation, whether it reaches the fully open state can generally be determined by the opening height. Usually, when it reaches the fully open state, its opening height is about one-third of the nominal diameter. Therefore, in practical applications, we need to pay attention to the formation of the valve disc to determine whether it has reached the fully open state. In addition, its valve disc is generally used as an opening and closing member, and its shape is usually plug shaped. The sealing surface is generally flat or conical.

During the actual operation of fluorine lined check valves, the maintenance of sealing performance generally relies on applying a certain amount of force to the valve disc. Due to the friction between the valve stem and the filling component during operation, the valve stem must be thick enough to avoid accidents such as valve stem bending. So, in choosing PTFE lined valve When selecting, it is important to choose the appropriate valve stem diameter according to the requirements.
