Vented Paddle Blinds

A vented paddle blind can offer a safe way to release pressure, fluids, or gasses from a piping system while providing a convenient port for hydrostatic or chemical testing.

Understanding Vented Paddle Blinds

A vented paddle blind features one face that is completely solid and one that features a small hole or vents bored into the surface that creates a passage to the exterior of the blind. Unlike a standard paddle blind that blocks flow in both directions when it is inserted between a pair of pipe flanges, the vents paddle blind blocks flow in on one side and allow a small amount of flow through the vent on the other side.

This can be used to pressure test the pipe, take samples of the gases or liquids, bleed off the air, or relieve pressure in the piping system. An external valve can be added to safely remove gases or liquids from the pipe without the risk of leaks or spills.
