What is the difference between ball valve and butterfly valve?

Ball valves and butterfly valves have significant differences in many aspects. The following are the main differences between them: I. Structure and Working Principle Ball valve Structure: It is composed of components such as the valve body, valve core (ball), and valve stem. The ball is driven by the valve stem and rotates around the axis of the ball valve, thereby controlling the on-off of the fluid. Working principle: The flow of the pipeline is cut off by blo

What is the difference between electric valves and pneumatic valves?

There are differences between electric valves and pneumatic valves in terms of power source, control performance, applicable scenarios, maintenance costs, etc., as follows: 1. * * Power source** -Electric valve: It uses an electric motor as a power source to drive the opening and closing of the valve. Electric motors usually use mains or other DC power sources, and as long as there is a stable power supply, electric valves can work normally.
