The difference between plug valve and ball valve:
1,Different structures: The valve core of a plug valve is cylindrical, while the valve core of a ball valve is spherical.
2,Different operating torques: The operating torque of a plug valve is greater than that of a ball valve because the valve core of a plug valve needs to move within the pipeline, while the valve core of a ball valve only needs to rotate axially.
3,Inconsistent sealing effect: Ball valves have good sealing performance, while the sealing effect of plug valves is affected by the gap between the valve core and the valve seat.
4,There are differences in applicable scenarios: plug valves are mostly used in situations with strict sealing requirements, and the diameter of the connecting pipe fittings is not large; Ball valves are suitable for situations where the sealing effect is not very strict and the connection diameter is large.
