Vented blinds/paddles block flow on one side, while allowing pressure relief on the other side. This helps create a much safer downstream work condition.

Mac-Weld vented blinds/paddles provide an economical solution, when a valve isn’t available near your work site. Vented blinds have multiple benefits including easy access to hydro-testing, purge entry point and line pressure release.
