Product Description

When the fluid passes through the gaps of the opening and closing parts in the pipeline, the operating force needs to overcome the resistance caused by friction and sealing surfaces, which is called friction; When the additional stress generated by factors such as time-varying loads and temperature changes is within the allowable design range, it is called subjective tightening torque or pre tightening pressure. The function of this force is to tightly press the closed part onto the open part and maintain a certain correct positioning, in order to prevent damage to the sealing performance
