Designed to blind pipelines, either temporarily or permanently.
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.
Looking for a custom port location, our team of designers are on hand to help you manufacture the part to your specifications. Also known as a bleed, spade or slip blinds, we offer a large variety of sizes and materials to suit your project requirements.
