Hygienic ball valve temperature pressure view description

The sanitary ball valve chrome plate shows the maximum operating pressure allowed for the ball valve at maximum and minimum operating temperatures. If PTFE or RTFE ball valve seats and seals are used, the operating temperatures of other types of seats and seals should be checked.
The nominal pressure rating (PN) of the ball valve indicates the maximum working pressure of the valve at normal temperature. (Example: PN4.0, indicating that the maximum operating pressure at an operating temperature of -290C to 380C is 40 Bar (4.0 MPa)). The precautions for electric ball valves or pneumatic actuators are detailed in the corresponding instructions.
