USA Industries' EZ Vent® Slip Blind is similar to a Paddle Blind, with one major difference. Typical paddle blinds block flow on both sides of your flange, which can lead to pressure or fluid building up on one side of the flange. This ventable blind allows you to block flow on one side of the blind while allowing access to relieve or purge the other side. This makes downstream work much safer in the event of a leaking valve upstream.
The EZ Vent Slip Blind (also referred to as a bleeder blind) is useful if there is not a valve on your piping at a location near where you're working. A ventable blind is the easiest way to verify that there is zero energy in the line, vent off any pressure that has leaked by upstream valves, or create an entry point for hydrotesting.

Note: USA Industries has started placing all NPTs 180° from the handle. Typical installation would have the handle pointing up, and the port draining down out the bottom. If you require custom placement of your NPT port from the handle you must specifically request it.
Yes, multiple ports can easily be added, and we can add them on both sides upon request! Please specify how many and whether you want them on the upstream or downstream side of the blinds on your quote request.
Sometimes. For every NPT or Socketweld blind, there is a minimum thickness required, which is also determined by whether or not the blind needs to be rated for pressure. We can easily make your blind thicker to meet custom needs.
No. Our internal standard is to place the port at approximately 180 degrees from the handle with no interference between the connection and the bolts. However, if you need the connection point in a different location on the blind, we can manufacture it to your specs.
When requesting an alternate port placement, we recommend that you specify where in relation to the handle you would like the port(s) to be located (ie. approximately 90 Degrees from handle) and note that the vent must be located between bolt holes.
Yes, just let us know your requirements. We can completely customize our products to your needs, and we regularly finish our blinds with a Machined 125-250 rms finish or an RTJ (RJ) for the gasket area.
