The nameplate shows the maximum allowable operating pressure of the ball valve at the maximum and minimum operating temperatures.
The operating temperature of PTFE or RTFE valve seats and seals and other types of valve seats and seals shall be checked by KI factory.
The nominal pressure rating (PN) of the valve can indicate the maximum working pressure of the valve under normal temperature. (For example, PN4.0 indicates that the maximum working pressure is 40 Bar (4.0MPa) when the operating temperature is - 190C~380C).
Please refer to the corresponding instructions for precautions of electric or pneumatic actuators.
