Better Than Bellows PRVs

 Reduce Maintenance Costs, Improve Reliability, Increase Safety, and Lower Emissions

Reduce Maintenance Costs, Improve Reliability, Increase Safety, and Lower Emissions

The Crosby J-Series with Balanced Diaphragm technology minimizes these risks by replacing the bellows with a flexible reinformed elastomer diaphragm. Diaphragms are inherently more resilient for higher backpressures and rapid pressure cycling applications. As a result, our new technology extends the backpressure limits to 80% of set pressure and increases the Kb factor up to 15%—expanding the application range of spring-loaded PRVs.

The Crosby Balanced Diaphragm Checks All the Boxes

  Reliability: Robust design ensures balanced operation
  Productivity: Extends backpressure handling while improving Kb factor
  Safety: 100x more resilient than metal bellows for high frequency cycling
  Environment Friendly: Maintains reliable protection against fugitive emissions
  Cost Effective: Yields long-term cost savings relative to PRVs with bellows installed

Already have existing Crosby J-Series PRVs in place?
You can easily convert them with our Balanced Diaphragm upgrade kits.
