The butterfly valve is a simple regulating valve. The butterfly valve that can be used for the on-off control of low-pressure pipeline media refers to a valve whose closing member is a disc, which rotates around the valve shaft to achieve opening and closing. The editor of this article first talk to you about how to distinguish between butterfly valves and gate valves:
1. Advantages:
Gate valve: It has a straight flow path with low fluid resistance.
Butterfly valve: has a straight flow path, fast opening and closing operation, simple operation, light weight and compact;
2. Disadvantages:
Gate valve: Larger size, longer opening and closing operation time, only limited to fully open-fully closed use.
Butterfly valve: using soft seat material, the temperature and fluid that can be used are limited
3. Valve body action:
Gate valve: Sliding, a method in which a plate-shaped valve body slides in a direction almost at right angles to the flow direction.
Butterfly valve: Rotation to make the plug-shaped, spherical, plate-shaped valve body rotate;
