The nameplate shows the maximum allowable operating pressure for the ball valve at the maximum and minimum operating temperatures.
Seats and seals made of PTFE or RTFE are used. The operating temperature of other types of seats and seals should be checked by the KI factory.
The nominal pressure rating (PN) of the valve indicates the maximum working pressure of the valve under normal temperature conditions. (For example: PN4.0, indicating that its maximum working pressure is 40 Bar (4.0MPa) when its operating temperature is -190C ~ 380C).
For the precautions of electric or pneumatic actuators, refer to their corresponding manuals.
