The following text is the transcript of the Air Logic educational video on umbrella check valves.

 

 

What we’ve been making a lot lately is umbrella check valves.

How the Umbrella Check Valve Works

If you don’t know how an umbrella check valve works, it’s shaped like an umbrella of course. You apply pressure in some through-holes and then as that pressure increases the umbrella is going to lift up, just like a big umbrella in the wind, and your flow is going to go around it.

Air Logic’s In-house Designs

These are both just a nice design, and they’re also well suited for us. We design and manufacturer both our own tooling and our own plastic parts here at Air Logic. We can control a lot of the aspects of the umbrella check valve design; that includes how thick the center section is inside of an umbrella check valve, the surface condition, how much we let the overall movement happen.

Customizable Flow Control Solutions

We’ve been having a lot of success with those on the low cracking pressures and also dialing in an exact cracking pressure. We have standard cracking pressure, something like 3 inH2O or 0.11 psi, and then people will come to us and say “Hey can you do 0.2, can you do 0.3?” and so we can make those adjustments inside the check valve. And we just get great performance out of it, because again we have a hard seat inside there with a nice soft elastomer. We can adjust a lot of different factors inside the umbrella check valve to make it work how our customers need it to.
