THE CHECK VALVE DESIGNED EXCLUSIVELY FOR ANAEROBIC DIGESTERS

US PATENT: 12,281,713

Bio-Check Solves the Anaerobic Digester Liquid Problem

BioCheck Biogas Digester Check Valve

You're in the business of selling gas, right?

  • If you have a Meat or Dairy digester, you’ve got gas and liquids. But you’re in the business to sell gas not the liquids in the digester. Southern Valve & Control has designed and patented the world's first check valve exclusive to the digester industry.

Costly Shutdowns?

  • Does gathering liquids result in unnecessary, costly shutdowns of your equipment? We’ve got the solution. Bio-Check a Southern Valve & Control innovation will make those shutdowns a thing of past.

What Sizes Are Available?

  • 150# flanged sizes from 4-8” 
  • (other sizes POA)

What's it made of?

  • Bio-Check is Made of Machined 300 Series Stainless Steel and using Viton Elastomers, Bio-Check Meets NACE requirements for H2s and other damaging gases associated with Methane production and gathering.

How's Does Bio-Check Work?

  • Bio-Check works on a similar principle as a float check, but accounts for things like density, water level in the digester, the ability to shut off gas flow before gas enters your gathering system and ability to break vacuum mechanically when water levels return to normal operation.
