Spring-type check valve and float-type check valve?
Thread Content
The company has been carrying out on-site installations recently, and there are two specifications in stock. One is a spring-type check valve, and the other is a float-type one. Is there any difference in their installation direction?
Spring-type and float-type valves belong to the category of lift-type check valves; if the flow direction is not indicated on the valve body, it can be determined by looking at both ends of the valve – the side with the lower pipe opening is the inlet.
Spring-type check valves belong to disc-type check valves, while float-type check valves belong to lift-type check valves. It is best to install both types of check valves in a horizontal position
Check valves have a direction in which they should be installed; generally, an arrow is indicated on them to show this direction.
