UVU Overflow Valves

DA Flow Indicators

Flow indicators for monitoring the outlet of dual safety valves.

AWP flow indicators are designed for installation on the outlet of dual safety valves and protect the safety valves from foreign substances or moisture by using a special liquid which is contained in the flow indicator. They are used for checking the safety valves for leaks and to check that the safety valves are operating properly.
