FAQ：
Q: What is the purpose of a check valve?
The main purpose of a check valve in a system is to prevent backflow, which could damage equipment or contaminate media upstream.
Q: Why is my check valve not working?
When a check valve doesn't work, it allows backflow. Three possible reasons for this are: sticking, leakage, or slow closing. If there isn't a filter in the line, dirt or debris can be trapped between the disc and body keeping it open. Due to wear or corroding media on the material, the disc or seat can become damaged or torn preventing a proper seal and allowing backflow. If the valve closes too slow, minimal backflow can enter before a proper seal can occur. Ensure that gravity is helping the design, and/or your spring is quick enough to close the valve rapidly.
