Gear Operated Flange Ball Valve
Short Description
Classification characteristics
Ball valves are divided into floating ball valves, fixed ball valves, track ball valves, V-shaped ball valves, three-way ball valves, stainless steel ball valves, cast steel ball valves, forged steel ball valves, dusting ball valves, sulfur-resistant ball valves, pneumatic ball valves, electric ball valves, clamp sleeve ball valves, welding ball valves.
The nameplate shows the maximum operating pressure allowed by the ball valve at the maximum and minimum operating temperatures.
Seats and seals made of PTFE or RTFE materials and operating temperatures of other types of seats and seals shall be checked by KI plant.
The nominal pressure level (PN) of the valve indicates the maximum operating pressure of the valve at normal temperature. For example, PN4.0 indicates that the maximum operating pressure is 40 Bar (4.0 MPa) when the operating temperature is - 190C - 380C.
Notes for electric or pneumatic actuators can be found in the corresponding instructions.
