COMAP check valves give control over water flow direction, allowing fluid to pass in the A-to-B direction while preventing it from flowing in the other direction.
Benefits of check valves
- Prevents contamination of the system
- Drainage of the mains upstream and downstream
Applications of check valves
Downstream pressure can increase due to expansion of the fluid in a circuit, causing water backflow. This is when the check valve comes into play.
