Do you know? Stainless steel ball valves have restrictions on their use in terms of temperature and pressure.
The nameplate on the stainless steel ball valve states the maximum allowable operating pressure of the ball valve at the maximum or minimum operating temperature; for valve seats and seals made of PTFE or RTFE, the operating temperature range is -290~2000°C, and other types of valve seats and seals The operating temperature of the parts should be checked by the KI factory.
The nominal pressure grade of the stainless steel ball valve can indicate the maximum working pressure under normal temperature conditions (such as PN4.0, indicating that the maximum working pressure when the operating temperature is -290-380°C is 40 Bar (4.0MPa)).
