Check valves

Check valve threaded brass 1270

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.
